[Bug 76902] Re: Switch user crashes system.

[Malius]

I just tried the same proceedure with gnome-screensaver.  The system
logs did not report anything during a crash.

BTW, I do not think the error message stated above has anything to do
with the problem at hand (Researched the issue on the Net).

The only common denominator at this point is:
gdmflexiserver -s

Is there a way to debug this?
