Bug 241916

Application: dolphin (1.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
1: Open a folder full of images. I used the folder containing the famfamfam silk icons (google it).
2: Make sure dolphin is set to preview the images and view is set to icon mode (may not be necissary).
3: Browse a while. This can sometimes be a few seconds or sometimes several minutes (and sometimes it doesn't happen).
4: Crash.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
