I added myself to the CC for that bug.  Thanks for the pointer.  I
haven't tried anything else, though, like applying your patch.

When this bug hits me, it seems to be after my other bug strikes
enough times that I have a bunch of gdm sessions running.  Maybe I'm
running out of resources at that point.  I've been getting in the
habit of periodically killing all metacity processes, and those
gdm-simple-slave processes not associated with my session (wish I
could just easily kill them all).

At the moment, it always starts a new X server, so I can't verify that
it hasn't been my imagination.  The DPMS stuff is the least of my
troubles at the moment!  If I can get the rest working properly, I
will come back to this issue.

That's probably true.  It hasn't been easy to find documentation;
maybe I've been looking in the wrong places.

Thanks for your help and feedback.
