Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.5 (KDE 4.5.5) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.37-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
The Plasma desktop was frozen (mouse pointer working, but no effect on window or desktop, even Alt-F2 was not working).
I logged in with to another console with Ctrl-Alt-F2 and executed killall plasma-desktop, that worked.
But I was not able to start plasma-desktop for the running X session again (did not know how to start it for the current X session from another console).
Therefore I executed Ctrl-Alt-Backspace inside the X session, X session exited.
Then I switched to the first console (where I started X after booting the PC) and executed startx again.
Inside the new X session, the plasma-desktop was still not running (no taskbar) so I pressed Alt-F2, the command dialog appeared this time and I executed plasma-desktop.
The plasma-desktop immediately crashed, leading to this bug report.

-- Backtrace:
