Application: gwenview (2.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic-pae i686
Distribution: Ubuntu 12.04 LTS

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

I was viewing an album containing .jpg photographs as well as .mp4 streams of the following type:
2012-07-10 14.55.12.mp4:   ISO Media, MPEG v4 system, version 1

I browsed a dozen photographs and about three videos fine, but on the fourth video gwenview froze, started taking up 100% CPU, and eventually crashed.

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