Application: kwin (4.9.1 "release 561")
KDE Platform Version: 4.9.1 "release 561"
Qt Version: 4.8.2
Operating System: Linux 3.4.6-2.10-default i686
Distribution: "openSUSE 12.2 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I disconnected the mouse and keyboard from the computer and later plugged them back in. After that mouse worked normally but keyboard didn't work until KWin crashed (and recovered automatically) about 10 seconds after the keyboard was plugged in.
Also the monitor was turned off while mouse and keyboard were disconnected (I was connected to a different computer for some time before going back to this one).

I don't know if the keyboard had anything to do with the crash but at least the crash info should be useful to see if this was caused by a bug.

I also probably wont be able to reproduce the crash, since I have no idea what could have caused the problem.

Feel free to contact me to do any test or to try to reproduce the bug if you need me to ... I am also a programmer and I am familiar with Linux so I might be of some use :)
