Description Gabriel Werner 2012-06-25 11:54:07 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.4 (4.8.4) "release 6"
Qt Version: 4.8.2
Operating System: Linux 3.4.2-29-default x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Rightclick the configurationbutton of the Panel and remove it(moved it from bottom to top before)

- Custom settings of the application:
My Panel was not working right ("Starter" - kind of quickstart symbols extending to a window - couldn't be removed, so i added a new panel, moved the old one and removed it then, instantly plasma crashed and then)

If I try that with a new panel it doesn't crash

I hope i gave you enough information :)
