Description Denis 2012-10-30 20:30:20 UTC
Application: kwin (4.8.5 (4.8.5))
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.0.0-23-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
just run apt-get upgrade on kubuntu precise and got this issue
I found similar bugs, but not really same
it works fine if i use only one screen, and fails when trying to connect second one

The crash can be reproduced every time.
