I'm debugging a gstthread pipeline started from nautilus.
The nautilus part sets up the pipeline correctly, puts it inside a thread
and sets it to play.

GStreamer doesn't actually play, the threads seem to get iterated but they
give no status back and the debug output keeps mentioning the thread didn't
do anything and tries to see if it should finish the thread.

Look for the following string

** (nautilus:2409): WARNING **: PLAYING PIPELINE: 0x824c330

in the attached debug log.  That's where the pipeline is set to play, and
before that you see all the elements being set to play, and after that the
thread idles.

I have no idea what should be done here, I checked the bin code and it has
something commented that looks like it might be important.
