Bug 317274

Application: kwin (4.10.1)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.4-202.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Kwin crashes at logon.
This is only since a reinstall of Fedora 18, one week ago, 17 March 2013, everything was working OK and the system was (probably) up to date.

I have a dual monitor setup, as reported in bug 308369, if a start up with one monitor disconnected there is no problem. Also if desktop effects are disabled at startup there is no problem even with both monitors connected. Desktop effects can be enabled with Alt+Shift+F12 and everything works as normal.

The crash can be reproduced every time.

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