Bug 323679

Application: plasma-desktop (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-27-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed: After clicking on Unlock Widgets, I then clicked on the Cashew in the panel to adjusting the hight of the panel. I adjusted the hight, then clicked in a clean Desktop to clear the above action when the crash happened

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
