Yes, I set the pipeline state to GST_STATE_NULL.

Yes. each time I get a message with gst_bus_timed_pop I also unref this
message and after leaving the event loop I also unref the bus.
I appended the source code of my player program.
Should I also send the source of the two elements I programmed? They use
a proprietary library which I can't publish.
