Bug 314515

Application: kwin (4.9.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed: Logging out, rebooting or shutting down my Kubuntu 12.10 installation. This always happens and it is since I upgraded from Kubuntu 12.04 to 12.10. Please fix this with an automatic update or upgrade.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
