Application: kwin (4.10.5 "release 1")
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

it starts to begin annoying... same crash afer/while playing an opengl-game, same crash-context (kwineffects.cpp) . may be, disable kde-effects at all?
when sending error report, does kwin starts then new after report?

- Unusual behavior I noticed:
ok, not really unusual, but was surprising that meta+s stops the activities ! thought, i lost my desktop! .... will change this shortcut, because in "mc" alt+s is searching and alt key direct near meta key. should be a WARNING ala "do you really want to stop the activity? imho... although this sounds a bit like windows ;)

-- Backtrace:
