Description Northsoft 2013-07-17 13:28:49 UTC 
Application: kwin (4.8.5 (4.8.5))
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.4
Operating System: Linux 3.4.52-desktop-1.mga2 x86_64
Distribution: "Mageia 2"

-- Information about the crash:
- What I was doing when the application crashed:
1. Screensaver was active.
2. I've entered password and unlocked system.
- Unusual behavior I noticed:
3. Composition is down, KWin crashes, no titles and control buttons there
4. I start konsole and call kwin & from konsole, and after calling Ctrl+Shift+F12 to reenable composition KWin crashes.
Asus N61Jv, Intel i5 520m optimused with nV.GTX325m.

The crash can be reproduced some of the time.

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

"kcmshell4 kwincomspositing", 3rd tab - is  "suspend compositing for fullscreen windows" checked? Can you still reproduce this when unchecking it?
What about entries in /var/log/Xorg.0.log (for the KWin maintainer, the synaptics driver flooded the X11 event queue, leading to a hung GPU)
