That's an error of gstreamer itself.

At first sight I would say that you are not using pulseaudio on your system,
since it seems gstreamer cannot connect to the pulseaudio streamer.

Try changing "pulsesink" with "osssink" or "alsasink" in the gst_parse_launch call.

If none of those help, I'm also at a loss: I am not a gstreamer expert...
