Badly interleaved AVI file not handled

Description
The broken file is available at streams.videolan.org/issues/ffmpeg/yet-another-broken-interleaved-avi.avi.
The file seems correctly interleaved, but around 01:08, only video packets seems to be decoded. While MPlayer AVI demuxer is able to handle it ("Badly interleaved AVI file detected - switching to -ni mode..."), FFmpeg AVI demuxer doesn't.

Since it works fine here, could one of you add a command line that allows to reproduce the problem together with complete, uncut console output?

That's about 50 seconds in. A-V difference keeps getting worse from this point. The ALSA warnings are merely because ffplay doesn't feed it enough audio, and not a problem with my audio setup. File is linked in the top post.

So what's the difference? How to proceed? Just to be sure, I made a clean build of ffmpeg with no additional config option. Output with -loglevel debug:

My test file was cut short (I probably wanted to save some space...). You can create a test file with:
dd if=yet-another-broken-interleaved-avi.avi of=test.avi bs=1048576 count=200
Note that this is almost the full file. md5sum: 96accaf5878be60f076a50038f85339c
mplayer -demux avi handles this fine (even without -idx, although it requires -idx for seeking), ffplay doesn't.
Shall I create a new ticket for this problem, or can I leave this ticket open?

Please open a new ticket.
Note:
See TracTickets
for help on using tickets.
Works fine with ffmpeg and mplayer -demuxer avi, fails with ffplay and mplayer -demuxer lavf.
