Hi,

I'm just in the process of setting up my new computer with Windows XP.  I
installed the latest MikTex and LyX, opened my first file which I created in
version 1.6.0, scrolled down, and it crashed in exactly the way you
describe.  Three eps figures were causing me problems, and it turns out that
they had all been scaled to 50%.  All three were the same size at 1009x756
pixels, in landscape orientation.  Scaling to 49 or 51 % does not cause the
crash.  I can email you one of the files if you like.

As an aside, every time I save the preferences, the maximized LyX window
shrinks to the previously unmaximized size, but the border remains
unsizable.  I have to click restore and then maximize to get back to using
the full screen.

While I have your attention, I am still at a loss why I can't get a response
from the lyx ftp server.  If any of you have any ideas to offer in response
to my query several days ago I would greatly appreciate it!

Thanks!

Anton

 Using Vim, I replaced bookcover.eps with bookcover.pdf, a much smaller

 So here's my question for everyone reporting 1.6.x crashes: Did your files
 include graphics? Did they include large graphics? Were any of the large
 graphics .eps files? Was there anybody suffering a 1.6.x crash whose file
 DID NOT
 have graphic files?

 If there's anyone currently able to reproduce this problem, would you be
 able
 to use a text editor to whittle the file down to a small reproducer, and
 then
 use the text editor to toggle the symptom by enabling and disapbling the
 big
 graphic?

Steve,

A lot of the crashes that were reported actually came from people that 
were using Ubuntu 9.04. The problem was that Ubuntu was shipped with 
Qt4.5.0, which had a number of bugs (at least in combination with LyX 
that is). I know you don't want to fiddle around with your fresh new 
installation, but if you still have Qt4.5.0, I'd advice you to upgrade 
to Qt4.5.2.

I'm not sure that *all* crashes on Ubuntu are related to Qt and 
graphics.  I've had a couple of crashes lately working on a document 
whose only images are generated by xypic (so the images are external TeX 
files that are added to the doc by LyX input commands, with instant 
preview off).  The most recent one, at least, occurred when I cursored 
out of a math inset and then immediately changed my mind and tried to 
reenter it via the left arrow key.  (I might have deleted a character 
along the way; don't recall for sure.)  I suppose that could still be a 
Qt issue, since Qt handles the LyX GUI itself.


Personally, I'm just going to live with it until the updated Qt version 
finds its way into some repository as a .deb package.  Fortunately, I 
deal with short documents, so restart/reload is not too painful.

 was a reproducible error -- it happened every time in the same amount of
 time.

 Using Vim, I replaced bookcover.eps with bookcover.pdf, a much smaller
 file, and the problem disappeared.
 So here's my question for everyone reporting 1.6.x crashes: Did your files
 include graphics? Did they include large graphics? Were any of the large
 graphics .eps files? Was there anybody suffering a 1.6.x crash whose file
 DID NOT have graphic files?

 I'm not sure that *all* crashes on Ubuntu are related to Qt and graphics.
  I've had a couple of crashes lately working on a document whose only images
 are generated by xypic (so the images are external TeX files that are added
 to the doc by LyX input commands, with instant preview off).  The most
 recent one, at least, occurred when I cursored out of a math inset and then
 immediately changed my mind and tried to reenter it via the left arrow key.
  (I might have deleted a character along the way; don't recall for sure.)  I
 suppose that could still be a Qt issue, since Qt handles the LyX GUI itself.

 Personally, I'm just going to live with it until the updated Qt version
 finds its way into some repository as a .deb package.  Fortunately, I deal
 with short documents, so restart/reload is not too painful.

Well they are in the Karmic repositories. Instructions on how to
upgrade qt4 (fairly) safely are at:

http://www.mail-archive.com/lyx-users@lists.lyx.org/msg74482.html

Scroll down past my instructions and follow Michael Gasper's clearer,
better instructions.

These instructions have worked for me and Michael without any files
being eaten. The main things to remember are to watch the upgrade to
make sure it it only upgrades qt4 related packages, and disable the
Karmic repository after you use it (so you don't accidentally upgrade
to Karmic next time you do updates).

use the text editor to toggle the symptom by enabling and disapbling the big 
graphic?


  

Steve,

A lot of the crashes that were reported actually came from people that 
were using Ubuntu 9.04. The problem was that Ubuntu was shipped with 
Qt4.5.0, which had a number of bugs (at least in combination with LyX 
that is). I know you don't want to fiddle around with your fresh new 
installation, but if you still have Qt4.5.0, I'd advice you to upgrade 
to Qt4.5.2.


The best thing that I can think of in your case is that you have run 
into bug #5957: If you scale down an image with an odd number of rows to 
50% (on screen), Qt4.5.0 would crash. I've used much larger eps graphics 
which didn't show your problem (on Windows).

Thanks
