Application: dolphin (1.5)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-30-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I drag&dropped a file from Dolphin to GIMP. Both windows are fullscreen so I moved the mouse over the taskbar to change the window. Dolphin and Gimp crashed when GIMP was almost ready seen (but no content in the toolbox) and I released the file.

The crash can be reproduced some of the time.

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