Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
First of all, I noticed strange behaviour while using dolphin. The width of the places panel does not seem to be remembered after closing dolphin. No matter what I did, every time I opened dolphin I would have to resize the shrinked places panel. I also tried deleting ~/.kde/share/apps/dolphin/dolphinui.rc but it did not help to solve the problem.

What was happening when dolphin crashed:
I tried to move "information panel" over the "places panel".

The crash does not occur every time, and I have not been able to reproduce exact steps. It seems to me that after resizing shrinked places panel, and putting information panel over it the Dolphin crashes.

The crash can be reproduced some of the time.
