Bug 273988

Application: plasma-desktop (0.4)
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:
Had kopete open for some time (jabber and ICQ), then closed it with right click on system tray icon->Quit. Then, plasma crashed unexpectedly.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
