What I did to get this
----------------------------
This is on a newly installed system. I connected my camera and nothing happened
I then checked the docs and found I had to install F-Spot in order for auto "Import" auto run to work
I installed F-Spot and then connected the camera, still nothing happened
I then just clicked the "+" sign and saw that the camera was being detected.
When I click "Import Button in the Import window, it died.
I ran Fspot in terminal mode and scanned the output and found that this line

Followed by

My camera did not appear in the File System

[z0man (z0manifest)]

Apologizes for the duplicate entry and the minor grammar "Please attached log for full stacktrace",

 Ubuntu LaunchedPad looked like it halted, I'm a first time bug submitter. And the correct grammar is "Please see attached log".

[z0man (z0manifest)]

Eek I said, "LaunchedPad"...

Ok I did another two tests and found that "Importing Folders" does the same thing.

I have attached another log file for that enviornment.

(/usr/lib/f-spot/f-spot.exe:2572): GdkPixbuf-WARNING **: GdkPixbufLoader finalized without calling gdk_pixbuf_loader_close() - this is not allowed. You must explicitly end the data stream to the loader before dropping the last reference.

Please see "Crash Log - Folder Importing"

[Chris Halse Rogers (raof)]

Ok. The GDK-Pixbuf warning is a harmless red-herring.

The crash here is in destroying some of the F-Spot widgets, which use GLX. I suspect that this is actually a bug in your graphics drivers.

Could you please try running this command in a terminal:
"""
LIBGL_DRIVERS_PATH=/nowhere f-spot
"""
and then try to reproduce the crash? That will disable 3D acceleration while running f-spot. I think that should prevent the crash. If that works, I'll move this bug to the appropriate place.

[z0man (z0manifest)]

Ok I did run that command you requested and attempted to try and retrace my steps to see if I can replicate the bug.

Soon I clicked "Import" it reset the Xserver so I had to re-login.

The Import worked!

I ran your command with the added Log recording

***
LIBGL_DRIVERS_PATH=/nowhere f-spot > fspot-newlog
****
Please see attached log if that helps try and understand why the "Import" resets the Xserver.

[Chris Halse Rogers (raof)]

Oooh, boy. Ok. This isn't an f-spot bug; anytime the X server crashes it's a bug in the X server :)

Could you follow the steps outlined here: https://wiki.ubuntu.com/X/Backtracing to get a backtrace of your X server crash? Thanks!
