Unfortunately the backtrace is rather incomplete. Please install the debug packages provided by your distribution and attach a new backtrace.

Please also check the rather long list of duplicates, if one of it already contains your crash.
Comment 2 Thomas Lübking 2010-12-17 20:46:45 UTC
debug packages won't help alot, because:

#11 0x00007f6273f17076 in __cxa_rethrow () from /usr/lib64/libstdc++.so.6
#12 0x00007f627514e563 in QEventLoop::exec (this=0x7fff900ebc30, flags=...) at
kernel/qeventloop.cpp:214

there's (once more and probably) an uncatched exception in the eventloop...
also none of the dupes really matches. however, it may be that we run into an invalidity related to the other tabbox crashes, plasma still attempts to render a frame and throws an exception (because the memory is corrupted and the parameters are thus borked) *shrug*

@Gaizka
- did some window close/disappear while you alt+tabbed?
- if you're lucky there's some output about the exception on the konsole (if you run kwin from there).
  If not, you'd have to recompile Qt unsetting the stupid exception support flag to get a "usable" crash :-(
Comment 3 sinozzuke 2010-12-17 21:17:30 UTC
Desperated for been unable to run far away from login, getting kded4 errors,
kwin crashes and all, this afternoon have deactivated all kde 4.6 and have
zypper dup for KDE 4.5 release 9. Sorry for that, I can't try again, but, if
you need too and it's a good clue for fixing something important, I can
install again 4.6 beta 2 for testing.
I love report bugs and help out, but I need my computer working too XD and
krita didn't run with that kde 4.6 buggy system. Sorry.
