   That isn't *all* that is borked, the realplayer plugin
in firefox/mozilla tanked, as well. All audio, no video.

  The same bug is just being announced in FC4, so I suspect it
is related.

  After a bunch of thumping around, one way or another,
an openly *stupid* addition got it working again...

  in unconfined.te add:
   allow unconfined_t usr_t:file execmod;

  So, as long as you don't mind leaving your armors backdoor
open, you can get this stuff working again.

  As far as acrobat, YMMV, but it worked for Realplayer.

  But, *my* it feels breezy in here...    :P

   I suspect a better fix than this is coming, as they repair the
selinux targeted updates they just released. Caveat Emptor.
