KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
consulting a floder with Dolphin, messaging with Kopete, closing both of them in this order.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal: Segmentation fault
