BTW, I have a hard time believing this is an issue that either PA or gstreamer 
is responsible for since banshee is playing files fine (and properly pausing) 
during VT switches.  I've been playing with banshee for awhile and cannot hang 
it in the same way rhythmbox does.  (I only have one of them open at a time too) 
  Seems like a bug to track down in rhythmbox itself.
