Bug 222570

Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.32-020632-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I had a dialog open in Quassel and a message came through - this would normally trigger a message in the notification area, but instead it crashed plasma-desktop.  Normally it works fine, but this time it didn't.

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