Application: dolphin (2.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I moved files in dolphin from one tab to another. If i have more than 2 tabs open in dolphin and i move files between them, i can practically wait for a crash to occur. Not immediatly, but it will happen. So it is basically reproducible. I had Firefox, Thunderbird, KompoZer and rekonq opened at the time of the crash.

The crash can be reproduced some of the time.

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