Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
My desktop were just starting up when WLAN Manager tried to connect   to WLAN . It took much more time than usual and couldn't connect. So I tried to select other Access Point and could't connect to any other WLAN. So I tried to connect the first WLAN, and in a second the whole Plasma crashed. And after that the WLAN worked as usual.

Thanks in advance !!!
