Can you confirm that this is also true for ffplay and that 
ffmpeg -i test.mkv out.avi produces an incorrectly playing file?

Where is this described?

Please test current git head, this is usually the only supported 
version (if you are a user and not a distributor), if the 
problem is still reproducible, consider opening a ticket on trac.

Please understand that the result of 
ffmpeg -i test.mkv out.avi is the primary indication for the bug.
