One way would be to try and come up with a minimal test program that
exhibits the issue, and then share it with us. It's a bit hard to help
without seeing the code, other than suggesting the things that have
already been suggested (valgrind etc.).
Do you do gst_element_set_state (pipeline, GST_STATE_NULL) as well when
shutting down? (before unreffing it)
Are you sure you unref all GstBus messages? (depends on context if
that's needed or not).
