Actually there is a better choice. Rather than change the context for
totem (and firefox and pitivi and rhythmbox and everything else that
uses gstreamer) you can just change the context of the pitfdll plugin
that is causing problems. It needs to exec its own modifiable memory
since it loads .dll files on to the heap, and then executes code that it
cuts out of them. Try this:

chcon -t texrel_shlib_t /usr/lib/gstreamer-0.10/libpitfdll.so


Cheers,
