KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-13-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
In "split view" i had opened two different directories (an external harddrive and a folder on my desktop) (both shown in column vide mode). 
After dragging a file from the desktop folder to the external harddrive the program segfaulted.

- Custom settings of the application:
In "split view" i had opened two different directories (an external harddrive and a folder on my desktop) (both shown in column vide mode).

The crash can be reproduced some of the time.

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