(run:14061): GStreamer-CRITICAL **:
Trying to dispose element autoaudiosrc0, but it is in PLAYING instead

You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
This problem may also be caused by a refcounting bug in the
application or some element.
