this is not a duplication of bug 614765,  it's introduced in fixing 614765.

What bug 614765 did is ref pulsesink before firing the pa_mainloop_api_once(), 
and unref the pulsesink in the callback.  This makes sure that the pulse
callback function is always called on a valid pulsesink.  BUT it introduce a
new problem,  if the pulse callback function is the LAST one being called,  it
will finalize the pulsesink and calling pa_threaded_mainloop_stop() from the
pathread,  which is prohibited, because if you take a look of
pa_threaded_mainloop_stop(),  it calls pthread_join(),  you CANNOT
pthread_join() with the same thread.
