While tracking down that bug, I found that the crash is due to improper
refcounting in gstreamer. Unless I'm missing something, the code path is all
gstreamer. It never hits totem.

See the test here at:
  http://p.mecheye.net/refcount/0

Notice how it incorrectly gets decremented to 0 during a message free, and is
then used later. (After its memory has been replaced by various pango stuff)

The gdb commands I used:
