You may have missunderstood the bug report. The original rmvb file works
with any player. After remuxing it to mkv with ffmpeg, no player can play
the mkv file (at least neither MPlayer nor VLC).
The actual bug seems to be in our mkv muxer storing invalid extradata for
real audio codecs.
But this patch at least prevent our demuxer to crash on those invalid files.
