Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Dolphin was open in last session, displaying two windows, one with the preview of a text file, the other with a perview of a Open Office speadsheet. Crashed on startup. I did have a crash the other day where I renamed a backup file to a text file and moved the mouse to preview the file.

The crash can be reproduced some of the time.

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