Bug#861989: nautilus: Nautilus freezes/crashes when right clicking and selecting properties for 1 or more files

[Luke Christopher Clarke]

Thank you Jason,

I have done the hard reset of the tracker database. I can now easily right
hand click and see the properties of the files. I do get the error
"GDBus.Error:org.freedesktop.Tracker1.SparqlError.Internal: Error opening
database" but I am assuming that this is because I have done the hard reset
and it will resolve itself if I leave my computer on for long enough.

Thank you very much for your help. I am happy to have this bug now resolved.

Regards
Luke

I forwarded this upstream and according to a tracker developer, the
nautilus tracker plugin will be going away soon, to be replaced a
feature directly in nautilus.

For a more immediate solution there are a few things you can try:

* Waiting for tracker-store to complete it's integrity check.  This
  could be several hours for a large database, possibly longer.

* Or, soft reset the tracker database with "tracker-control -e".  The
  tracker database will be deleted and restored from backup.

* Or, hard reset the tracker database with "tracker-control -r".  The
  tracker database will be deleted and recreated.

Hello Jason,

Sorry for lack of reply. Been away from my computer.

I can confirm that I do have a lot of photos in RAW format about 25Mb each.
However once I have finished with the images I then move them to a external
hard drive.

I will hopefully run the commands tonight.

Luke

I'm going to assume the answer to this is yes, you have gigabytes of

My understanding of sqlite's integrity_check is that can be slow, but
15+ minutes seems excessive.

How large is your tracker database ~/.cache/tracker/meta.db?  Do you
have gigabytes of documents being indexed that would inflate the
database?

It is odd that tracker-control freezes too.  I was expecting a message
about how the tracker store is initializing or reindexing.

   ^

This is supposed to be "tracker-control -k store".  The point is to kill
(-k) the existing tracker-store process before running tracker-store
with debug messages enabled, because otherwise it will just complain
that there is already a process running.

It looks like it's frozen because tracker is stuck.  What's the output
of "tracker-control -S"?  And what is the output of running
"tracker-control -k store; TRACKER_VERBOSITY=3 G_DEBUG=all

It looks like the problem is bigger than just the properties dialog since in
your video the nautilus window doesn't even appear the first time you run it.
Can you run nautilus with this command and post the output?
TRACKER_VERBOSITY=3 G_DEBUG=all NAUTILUS_DEBUG=all G_MESSAGES_DEBUG=all 
nautilus

Also, if you have installed any extra nautilus extensions, try removing them.

Bug#861989: nautilus: Nautilus freezes/crashes when right clicking and selecting properties for 1 or more files

[Luke]

Package: nautilus
Version: 3.14.1-2
Severity: important

Dear Maintainer,

Method
~~
1.) Open up Nautilus
2.) Navigate to a folder where you want to find the file size of contents
3.) Select the file(s)/folder(s), right hand click
4.) Click on the option "Properties" in the menu

Expected Results

Properties dialog will appear


Actual Results
~~
Nautilus will lock up, will not be able to use it even if I have multiple
windows opened. Eventually Gnome will inform me that Nautilus has potentially
crashed.
Other times, it has taken over a minute to load the properties dialog.

Notes
~
Does not happen all the time, about 50% for me. When it does occur Nautilus
will not open unless I either;
- Open using root permissions
- Use command 'pkill nautilus'

I can replicate this issue on two separate computers running Debian 8.7
