Application: gwenview (2.8.1)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.10-3.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I was in Dolphin in a folder full of png, I opened the first and started scrolling hitting spacebar, and then -after some (a dozen i'd guess)- it crashed. I tried another time, with the same condition but it hadn't crashed.

The crash can be reproduced some of the time.

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