Krash Handler output of kwnin crash

Description of problem:
kwin crashes after log out / reboot in combination with the nouveau-driver. This starts happening after an ABI rebuild of xorg-server and drivers [1] 

[1] http://lists.fedoraproject.org/pipermail/test/2012-July/109057.html

Version-Release number of selected component (if applicable):
* kde-workspace-4.8.97-2.fc18.x86_64
* xorg-x11-drv-nouveau-1.0.1-3.fc18.x86_64
* xorg-x11-server-Xorg-1.12.99.902-1.20120717.fc18.x86_64

How reproducible:
Since the update kwin didn't crash only once. I always reboot at the end of the day to Fedora 17. So mostly always.

Steps to Reproduce:
1. Log out of a kde rawhide install (upgraded fedora 17 liveCD)
2. Krash handler catches the crash
3.
  
Actual results:
kwin crashes, but everything works fine when de dialog box is closed.

Expected results:
kwin doesn't crash

Additional info:
Krash handler catched the crash, but IMHO this is a typical rawhide / development issue. Wrong? Note: the report was only rated with three stars. I suppose because some debuginfo packages were not available.

It's crashing in the driver,

Hi,

Hmmm ... The mass rebuild seems to have 'solved' the crash. So please close this report.

So it looks like something just needed a rebuild for an ABI change.
