I have seen this alert on F17 Beta RC3 i686 LiveCD. After I log out, gdm/X crashes. Probably abrt or some other process tried to inspect the crash. After the crash X respawned, logged me in, and I saw notification for this selinux denial.
Kamil filed a 'manual' bug for the problem caused by this, so closing as a dupe of that one, which is a blocker. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers *** This bug has been marked as a duplicate of bug 810451 ***
