Thanks for the report. Can you install debug symbols for libavcodec57
and get another backtrace?

Also what's the assertion you see on the terminal that causes the
abort()?

Do you have the same problem with gstreamer1.0-libav from experimental
(version 1.9.1-1)? I can't reproduce this here with either 1.8.2-1 or
1.9.1-1 unfortunately.
