Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-17-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
The panel would not accept any widgets.  After giving up trying to add widgets, plasma completely crashed.  Once plasma auto-restarted, adding widgets to the panel was now possible.

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