This looks as if it is the same (longstanding) bug as this, which is
only experienced by the caller:

https://bugzilla.gnome.org/show_bug.cgi?id=601882

The case reported there was with most of the then video codecs enabled,
including theora and h261 (of course the list of working codecs has
reduced over time as various things stop working as new releases come
out).

Judging by the length of time the earlier ubuntu launchpad bug has
stood, it looks to go back several years.
