+Summary: Crash in new gst_debug code
+
+Found this crash in with Marlin, but the Marlin code hasn't changed since
+before the new GstDebug stuff landed.
+
+Basic scenerio is GstThread hits EOF, Marlin changes the state of this
+pipeline to GST_STATE_NULL and this happens.
+I had to set MALLOC_CHECK_ to 2 to see the crash, otherwise, the
+application continues and eventually gives an X ASync error and dies
+shortly afterwards.
