Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
After installing a new comic to my comics plasmoid there was a still running notification with no name or anything showing.  I clicked on the stop button, closed it, then closed the top bar and plasma crashed.  This has happen before but since Plasma keeps coming back I didnt worry about it.  Still a small annoying little bug though.

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