Bug 287117

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I had clicked on the "desktop" icon in the top right corner, then clicked on "Add Panel" and then added a group panel, and then did the same and attempted to add all other types of panels and then KDE crashed upon adding the last panel.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
