Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.34-020634rc7-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
KDE 4.4.3, Kubuntu lucid. plasma-widget-networkmanagement 0.9~svn1112085-0ubuntu4.

I was connecting to a wireless network in my vincinity using the network management plasmoid, but the connection attempt stalled for unknown reasons that the plasmoid did not report. To force the attempt to stop and "reset" the interface, I unchecked the Enable Networking checkbox - at which point it immediately crashed plasma-desktop.

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