Application: gwenview (2.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

I was moving through photos in the thumbnail bar at the bottom of the screen, but when I selected a video there, gwenview crashed. gwenview was previously able to show these videos without any problems.

Let me also add that it took a very long time for gwenview to load in the first place; it took maybe 10 minutes from clicking on the picture to when gwenview actually opened. In that time, I installed and started using gnome's equivalent application...

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
