Application: gwenview (2.9.5)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-26-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed: browsing imagesand viewing slideshows  in GwenView

- Unusual behavior I noticed: During the slideshow sometimes it would flash an image much more quickly than the normal delay. Also during the blend in  transitions it seemed like it was getting stuck and I'd see two blended images on top of each other for longer than the transition was intended to take

- Custom settings of the application: No special settings for GwenView but I did just install AMD catalyst and the AMD APP OpenCL lib. As far as I could tell the installation when well and this is the first problem I've had

The crash can be reproduced some of the time.

-- Backtrace:
