Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-26-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
The title says it all. When I use the hardware switch to switch off the wlan (whilst being connected to a network) the desktop crashes. However, after a few seconds the desktop is restarted and all my windows are still there.

 -- Backtrace:
Application: Plasma-Arbeitsfläche (kdeinit4), signal: Segmentation fault
