.avi causing the crash


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.

Also, switching subtitles -> None in totem seems to deadlock the UI, but it might be the same issue.

This fixes the warnings and the deadlock for me.
