X server goes to 100% after logout of KDE session

[Orion Poplawski]

Brand new rawhide install....

I'm seeing a problem where after logging out of my KDE session where the 
screen goes blank and I can't access any VTs.  ssh login shows X running 
at 100%.  Strace shows tight loop of:

--- SIGALRM (Alarm clock) @ 0 (0) ---
sigreturn()                                                  = ? (mask 
now [])

Looks like there was a kwin crash process still running.

Anyone else see this?  Couldn't find anything in bugzilla.
