Bug 261576

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
My WLAN connection was lost, so I clicked on "SystemTray", where in the hidden section the Network Manager lives. I then clicked on the little icon representing "disconnect". Upon this Plasma/KDE Workspace crashed.

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