This looks like a problem in the X11 SELinux patches.

Comment 2 Eamon Walsh 2009-02-17 18:43:27 UTC

Caused by "DixUnknownAccess" being passed to dixLookupResource or one of the other lookup functions.  Need to find the callsite and change it to a nonzero access mode, e.g. "DixReadAccess" to reflect the purpose of the lookup.
