Application: plasma-desktop (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9.8-100.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Trying to add Lancelot launcher to the default panel. As it did not show up on first add I redid the action whereafter panel and gui bacake unresponsive. After adding the launcher, the panel and the desktop crashed.
- Unusual behavior I noticed:
The first added widget did not appear on the panel. Therefore I thought that I had not added the widget correctly and therefore added it again.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
