Bug 294899

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-7.fc16.i686 i686

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

I clicked the desktop tab in the upper-right hand corner of the screen, and clicked the plus beside "Add Panel".

I may have had Konquerer open at the time, but nothing else beyond whatever booted with the system (a minty-fresh install of Fedora)

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