Could you please take your time to report this bug upstream
following the guidelines here:
http://libav.org/bugreports.html. It really makes more sense if you
contact upstream yourself as they will definitely have some follow-up
questions.

Please also share the upstream bugzilla number as a reply to this
email, so that we can track progress done upstream.
