Looks like my fix for bug 539905 (Crash in SmcSetProperties() on exit) isn't working correctly and is itself crashing. I wasn't able to reproduce the situation in testing, so it was hard to be sure if it was correct. [ Creating this bug to duplicate all the ABRT filed bugs against ]

metacity-2.28.0-14.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/metacity-2.28.0-14.fc12
For reference, the problem problem was that though I added alternative correct code as an alternative to calling IceCloseConnection() behind libSM's back, I forgot to actually remove the call to IceCloseConnection(). As far as I know the update I just submitted to updates-testing should resolve this problem, though I still don't have a good way of reproducing the problem and testing fixes.
