I just had an issue with rhythmbox locking up while playing through pulseaudio. 
  It locked only when I switched to VT1 where root was logged in, and it 
immediately stopped playing and froze.  I've got the backtrace for all threads, 
but the top few are below.  The rest is rather long so I won't post it yet.  I 
haven't had rhythmbox do this before tonight.

Usually it will stop playing through the sink device (it is still trying to) 
until returning to the login that is running rhythmbox, but this time it 
actually froze and did not keep streaming to the sink.
