Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.00 (KDE 4.3.0) "release 152"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.25-0.1-default x86_64
Distribution: "openSUSE 11.1 (x86_64)"

What I was doing when the application crashed:
I opened Dolphin, switched into a subfolder of home, containing some more folders and some video files (note: there was an smb file transfer at that time writing files into that folder with my machine being the host). I then clicked on split, selected the left pane and then clicked on a Places item which I later found out belonged to a local directory that did not exist yet (i just reinstalled my system). The error message at the bottom of the screen appears for a few seconds and then Dolphin crashes.

I was able to reproduce it some times (and then only following exactly these steps) but not always
