Description irving 2012-05-07 23:09:16 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I added "Leave A Note" widget and I wrote something then I pressed "Leave Note" button and a crash dialog appears. The "panel" also disappeared for a while.

I had the default widgets plus "Notes" and "CPU Monitor"

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
