Unless I'm missing something It seems that mkvtoolnix is setting wrong Default
Duration for certain files with raw audio.

https://trac.bunkus.org/ticket/1001

This breaks timestamps in gstreamer since in this case default duration is used
to calculate lace duration. Other players seems to handle it find (either by
ignoring default duration and using block timestamp delta or possibly deriving
timestamps from the raw audio data).

Should this be addressed in any way? Unless I understand default duration wrong
the file is broken, however it plays with everything else.
