Application: kwin (4.10.2)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic x86_64
Distribution: Ubuntu 13.04

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

Just upgraded to Kubuntu 13.04, was setting my screen saver. Testing it I locked the screen, then when unlocking (horrible ugly unlock screen!) I came back to my normal desktop but with a crash message.

-- Backtrace:
Application: KWin (kwin), signal: Bus error
