Playing this clip with playbin2 from git leads to warnings and weird behaviour:

(lt-totem:5285): GStreamer-CRITICAL **: 
Trying to dispose object "text_sink", but it still has a parent "overlay".
You need to let the parent manage the object instead of unreffing the object
directly.


(lt-totem:5285): GStreamer-CRITICAL **: 
Trying to dispose object "src", but it still has a parent "parser".
You need to let the parent manage the object instead of unreffing the object
directly.

back trace of first warning:
