minimal pipeline exposing this bug
upon setting pipeline state to NULL at shutdown the following assertion is thrown repeatedly countless times:
GStreamer-CRITICAL **: gst_mini_object_unlock: assertion 'state >= SHARE_ONE' failed this is accompanied by wild disk thrashing and in the larger project where this was discovered it quite often also renders the entire system unresponsive where the only remedy is to pull the plug
i have isolated this behavior to a bin containing a pngdec and imagefreeze and ghostpad src to another bin
a .cpp file with a minimal pipeline exposing this is attached - a thread dump and valgrind profile is available in this gist along with the same .cpp file
