This is very likely bug #241163 - do you have an nvidia GPU?

To workaround:
set the scale method to "smooth" ("kcmshell4 kwincompositing" / "Advanced" tab)

Recent versions of kwin shouldn't show this anymore

Comment 2 mawerick 2011-09-12 19:01:13 UTC
Nvidia GPU was installed by OneClickInstall method. And one else. on hard disk i have two system-open suse and windows 7. system starting from Grub loader. loader has a timer which loads system by default (opensuse) if the choice between operation systems is not made. In this case plasma all time crash. If the choice is made, plasma crash with probability 50%. I do not know how these two events are connected.
Comment 3 Thomas Lübking 2011-09-12 20:04:52 UTC
It's a bug in combination between the nvidia driver (on some GPUs) and kwin.

-> Using "smooth" instead of "accurate" scaling will prevent the crash.

Since the return value is probably stored in the chip, it might be set differently/randomly. No idea. Doesn't matter either since recent version of kwin have a sanity check on the value.
