Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.36-1-generic i686
Distribution: Ubuntu natty (development branch)

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

I tried to disable wireless in plasma-widget-networkmanagement 0.9~svn1176084-0ubuntu1 and got this crash. Not sure if that's plasma or Qt..

The crash can be reproduced some of the time.

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