Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

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

Kubuntu fresh install on Sony Laptop and Intel i5 Sandy Bridge PC. On both everything works fine but not: Context Menu: Add Panel -> Default Panel. This one crashes on both fresh and fully updated installs.

Contrary to the main bug report, the crash does not appear when loging in. I can work fine if I don't use this context menu item.

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