It was set as invalid in Nautilus, because it is not a bug in Nautilus
itself, but rather a bug within the accessibility (ATK) libraries. That
is, this bug should manifest itself in other programs using GtkTreeView
widgets and with accessibility turned on.

This does not mean the bug will be neglected, only that the real cause
has been determined more precisely.

[Bug 359975] evince sometimes yield error Error printing: Too many failed attempts

2009-06-06 Thread vocx

Umang

The solution you pointed out is far from complete.
The blog post refers to Ubuntu 8.10. The new configuration file may be 
different. It seems more like bug #283811

The current bug seems to have (re-)appeared during the beta versions of
Ubuntu 9.04.

I suggest you let the developers track this problem in a better way.

For reference, a forum thread is here

Re: [Bug 364275] Re: Failed to print document / Too many failed attempts

2009-06-05 Thread vocx
Description:
When trying to print a PDF document with evince sometimes a dialog appears 
with the message
Failed to print document
 Too many attempts

and the document doesn't print any page at all.

While the messages Printing job..., Printing page... and
Finishing... are displayed at the top of the page, the evince process
consumes most CPU cycles.

The bug doesn't show a consistent behavior in that sometimes the entire
document may print fine, and other times it may fail to print a single
page.

The bug occurred with many different PDF documents, being 5 to 20 pages
long, and 200 kB to 3 MB in size, but it also shows with smaller
documents.

These PDFs were generated with LaTeX:
bug_evince_print_CMSS12_Type1.pdf (13 KB)
bug_evince_print_NimbusSansL-Regu_Type1 (14.1 KB)
bug_evince_print_Noname_Type3.pdf (17.9 KB)

With PDFs having Type 1 fonts it doesn't seem to fail.

With the other one it took half a minute and sometimes it would print,
and sometimes it would display the Failed to print document dialog.
The System Monitor shows heavy usage of gs (ghostscript) in this
instance.

The Manage Print Jobs application in Applications  Accessories shows
that those jobs with Type 1 fonts have a size comparable with the actual
file size, that is, with the example documents provided, they are around
35 kB. With the Type 3 document the size was 4024 kB. Other documents I
printed showed jobs as big as 8450 kB.

I encountered this bug only while printing from evince.

I tried printing from okular, and it never gave any problem.


My printer: HP Laser Jet 1015

Ubuntu 9.04

[Bug 354995] Re: Brasero Checksum Error

2009-05-25 Thread vocx
emarkay

About using growisofs instead of wodim, there seems to be some
confusion from Pedro Villavicencio.

Currently, Ubuntu 9.04, brasero (2.26.1-0ubuntu1) depends on wodim 
(1.1.9-1ubuntu1), and therefore is not possible to install brasero without it.
Besides that, I believe brasero actually uses one or another program depending 
on the media used, CD or DVD, and the type of data being burned.

I have logs that show that BraseroWodim is being used when burning a
CD-RW, but BraseroGrowisofs when the media is DVD-RW. You can see the
logs when running brasero in debug mode brasero -g

I also believe that the problem may not be brasero itself, but may be
with the underlying wodim, genisoimage, or other  packages. I
remember I had a similar problem with gnomebaker (0.6.4-1), which
resulted in a fixation error like that of bug #234521

Therefore, in order to really troubleshoot this a lot of testing needs
to be done. This is in fact the problem, because it means that you need
to waste several blank CDs or DVDs if you want to exhaust all the
possibilities and, of course, using rewritable (-RW) media is not
enough.

It's very important to notice the correct Ubuntu release, and whether it is a

In the original post it says Ubuntu 9.10, and then Ubuntu 8.14, which is rather 
confusing.

The package version is also important.

[Bug 316924] Re: Nautilus Loads Processor when there is an icons folder in the home directory

2009-04-22 Thread vocx
Well, I tried installing a few themes and I haven't been able to
reproduce this bug.

I installed the icon themes
Amora-0.4.1.tar.gz
SnowIsh-1.0.tar.gz (SVG)
SnowIsh-1.0_PNG.tar.bz

and the Gtk+ meta-theme
SnowIsh-Theme.tar.gz

I didn't want to attach the SnowIsh icon archives because of their sizes
(6 MB and 9 MB), but they are found easily on the web.



StewPedassle

It seems weird to me that the bug is caused by files that are in the particular 
folder $HOME/Theme/Icons
I suppose you created this folder to keep your downloaded themes organized.
But I also suppose that you know that themes are installed either manually or 
automatically (through the Appearance Preferences interface in System  
Preference  Appearance  Install) by extracting the compressed archive in the 
$HOME/.icons and $HOME/.themes directories, for icons and themes 
respectively.

That is, the $HOME/Theme/Icons folder should have no effect, it
shouldn't be searched. Maybe it is searched by something else? An
indexing service perhaps (trackerd)? A nautilus script? I don't know.

What I may suggest is to list the contents of $HOME/.icons and 
$HOME/.themes just to know what other themes there are. Maybe one of these 
other themes is causing the problem. Then you may backup these directories and 
delete them.
tar cvzf Themes-Backup.tar.gz $HOME/.icons $HOME/.themes
rm -rf $HOME/.icons/* $HOME/.themes/*

Then, without unpacking the tarballs, install the themes through the
interface as mentioned above.

1. If all goes well, you can now use the themes, and you don't have to worry 
about unpacking anything in $HOME/Theme/Icons
2. Even if everything went well, you may unpack the archives in that folder and 
try to reproduce the bug. Then you can play with it and see if you can 
pinpoint the problem. Delete *.png files, leave the *.svg, etc.
3. You should get other people to reproduce this bug. Otherwise it can't be 
confirmed, and can't be called a real bug. Maybe it is something very 
specific to your current setup.
4. I suggest you try this on the newer Ubuntu 9.04.

Chances are that this is magically solved by upgrading or by something
silly like removing the $HOME/.icons folder and reinstalling the
themes.

It's good news that the probable cause of this bug has been determined!
However, it is still a bug, you should not forget about that.

Try placing the directory back where it was and confirm that the bug is 
reproducible every time.
I hope you haven't completely obliterated those files from your system!
It's specially important for others to be able to reproduce the bug. See if it 
only occurs with certain files, like *.png, *.svg, etc.
You may attach the files that trigger this bug as a compressed archive, 
Themes.tar.gz, for instance.

This information is valuable to determine if it's a duplicate of another
bug, or if it's already know by the developers.

While reading your logs, it seems like you have some images in
Themes/Icons/... located in your home folder. Please try removing
those folders, and disabling the preview feature of nautilus.

Since I cannot reproduce this bug, I don't know what else to suggest.

Try reproducing this bug in several conditions. Try the different views:
list, compact, icon; disable and enable compiz; check for hidden files;
check file names with special characters.

Also check top or htop for any suspicious process. Are you running
any KDE program that could conflict with nautilus?

It seems to me that while you are in the debugger you hit Ctrl+C after nautilus 
has finished hogging your system. This is not good because it gives the 
backtrace of a sleeping process, which is not interesting.
You should interrupt nautilus while it is actively using the CPU.

I suggest running the debugger several times; each time you hit Ctrl+C
nautilus will be stopped at a different time and different backtraces
will be obtained. You can even do this in a single gdb run.

Instead of quiting gdb, continue and repeat the interrupting and
backtrace.

(gdb) continue
Ctrl+C again
(gdb) backtrace full
... etc.

Note how the at-spi-registryd process appears next to nautilus.

I'm attaching 3 gdb backtraces.

To obtain these:
1. Install debug packages nautilus-dbg, libgtk2.0-0-dbg, 
libglib2.0-0-dbg, libatk1.0-dbg.
2. Completely close nautilus with nautilus --quit
3. Run the debugger gdb nautilus as described here 
https://wiki.ubuntu.com/Backtrace
4. I try to open /usr/bin which is guaranteed to have at least 1500 files.
5. Nautilus will eventually load the directory, but you need to wait at 
least 2.5 minutes on a slow computer. The time increases with the number of 
files. 
6. Interrupt the process in the terminal with Ctrl+C. You may do this while 
nautilus is still unresponsive; if you wait for it to finish loading the 
directory you won't have anything interesting in the backtrace.

In the first backtrace the only library without symbols is
/usr/lib/gtk-2.0/modules/libatk-bridge.so, which is included in the
at-spi package, which also provides /usr/lib/at-spi/at-spi-registryd

7. To obtain the other two backtraces install the debug symbols for this 
library, which  are found in libatspi-dbg
8. Briefly looking at the source code in gail/gailtreeview.c, 
iterate_thru_children() is a recursive function, and according to one backtrace 
it is called a gazillion times.
9. The other backtrace shows a different output. You can run gdb several 
times to get different outputs each time, depending on the moment you hit 
Ctrl+C. I tested this on a single core, AMD64 processor, running 32-bit Ubuntu 
8.10. If you have a multicore machine, you'll see threads everywhere in the 
backtraces.
   10. Running valgrind with nautilus takes a LOT of time to even start. It 
outputs several lines concerning python2.5 and python libraries, which I 
believe is totally unrelated to this bug.

[Bug 316924] Re: Nautilus Loads Processor

2009-03-03 Thread vocx
StewPedassle

Your backtraces contain absolutely no debug symbols. Please install at
least nautilus-dbg, libgtk2.0-0-dbg, libglib2.0-0-dbg,
libatk1.0-dbg, and libatspi-dbg, and run the debugger again.

Make sure it is not the same as bug #159042, which is caused by the
Assistive Technology Service Provider Interface, at-spi.

[Bug 320993] Re: clock applet don't have any locations for Canary Islands

2009-01-27 Thread vocx
E. Guerra:

Thank you for clarifying the bug report. I see what you mean now.
Can you please update the description of the bug?

I tried what you said in Ubuntu 8.04.

Basically the bug is this:
1. In Ubuntu 8.04 if you search for Canary or Tenerife you'll find the 
location for Canary Islands, including timezone, latitude and longitude.
2. In Ubuntu 8.10 you have to search manually and you will only find the 
timezone.

It is somewhat like a regression, but it's really not a high-importance bug. 
Maybe the data files with the coordinates were incomplete or something.
I don't think developers would care much about fixing it in 8.10, however you 
should try the next Ubuntu release, 9.04, and make sure this doesn't happen 
again.

** Changed in: gnome-panel (Ubuntu)
Sourcepackagename: None = gnome-panel
   Status: Invalid = Confirmed
