Application: gwenview (2.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 2.6.37.6-0.11-default x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Opened Gwenview by double-clicking a PNG file in Doplhin.
Browsed through several files in directory (2089 files each monochrome PNGs with < 50 Kbyte)
pressed ESC to get to thumbnail view
clicked "x" in top right of window to close

Crash happened like this a few times, but not every time.

The crash can be reproduced some of the time.

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