Bug 237337

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 x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Clicked dolphin icon in panel; it crashed as soon as the window appeared.  Dolphin has been crashing frequently when deleting empty directories and simply navigating.  kdesvn is installed; this may be a factor.

The crash can be reproduced some of the time.

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