Previous kernel 2.6.11-1.1369_FC4 works without crashing. It does however print
the following messages when mounting:

  I verified that this happens when attempting to mount a blank DVD, but not
when mounting an already written data DVD.  It also happens for me when trying
to mount a video DVD.  I reported this in bug #162295.
