Small sample

This seems somewhat related to or fallout of bug 706066. Once it fails and you
try to decode audio on the same playbin afterwards, it aborts:

0:00:00.653888119 14135 0x7ff064003720 ERROR             bufferpool
gstbufferpool.c:491:gst_buffer_pool_set_active:<xvimagebufferpool1> start
failed

(png-audio:14135): GStreamer-CRITICAL **: Padname src_0 is not unique in
element streamsynchronizer0, not adding

(png-audio:14135): GStreamer-CRITICAL **: Padname sink_0 is not unique in
element streamsynchronizer0, not adding

ERROR:gstplaysink.c:3270:gst_play_sink_do_reconfigure: assertion failed: (it)
Aborted (core dumped)

To test, have a 4k by 4k png named sample.png and some audio file named
sample.mp3 in /tmp and run attached program.
