Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
- Unusual behavior I noticed:
Since upgrading to KDE 4.5 occasionally (a couple of times in a day's work) a process icon appears in the task bar. It has no title, just a large yellow X. When I place the mouse over it, an icon appears that looks most like a lipstick. Right-clicking gives the same options as ordinary processes, and I can send it to another desktop for instance. However, when I close the process, plasma desktop crashes and restarts (with this crash report wizard that I am now filling in).
 
All of my desktop widgets are still running at that point.

- Custom settings of the application:
None that I know of.

The crash can be reproduced every time.
