Python testcase (using GObject Introspection)

I've attached a test case which seeks in a file, waits a few seconds, then
attempts to reverse playback of the file. For mp4 containers (using qtdemux)
containing an h264 stream, this test case is fine. For AVI containers, the test
case freezes.

A sample file is available here:
http://www1.datafilehost.com/d/51ada03a

I've also reproduced this by remuxing Big Buck Bunny and using it with the
attached python script:

ffmpeg -i ~/big_buck_bunny_480p_h264.mov -vcodec copy -acodec copy
big_buck_bunny_480p_h264_remux.avi
