[Bug 67809] ksmserver crashes on logout w/ Xgl as session

[xinix]

Public bug reported:

Binary package hint: ksmserver

ksmserver crashes on logout with Xgl as session (where Xgl runs on top of X).  On logout there is a crash and a crash handler / backtrace opens for ksmserver.  This was not a problem earlier on in the Kubuntu Edgy releases, but I cannot remember when exactly it started.
Here's the back trace:
