Bug 207554

Application that crashed: kwin
Version of the application: 4.3.1 (KDE 4.3.1)
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
i use nvidia 190.18 (debian amd64) and kde 4.3 (hp dv7 laptop)
it happens rarely. i can not reproduce 

(seems duplicate of bug 198533 and 203830 and 185084)
