Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop i686
Distribution: "openSUSE 12.1 (i586)"

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

The panel and its icons still does not behave as expected (see bug 288101 ) so I decided to delete the complete main panel with all its applications and widget icons. So I right clicked on the main panel, on the top of the screen, and selected "remove this panel" and as a result this crash occured which in turn triggered the crash reporting assistant and finally the crash reoprt

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
