-- Information about the crash:
- What I was doing when the application crashed:

I accidentally removed the "Messsage Indicator" Appl second time, but didn't et and was trying to add it back, when KDS crashed. It did not crash the second time I tried, but did not add it either. 

THis is on Mint 12 KDE.

The crash can be reproduced some of the time.

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