This audio mp3 decoder is pretty old and has its bugs -
so you might try to switch to MAD  mp3 audio decoder.

Yeah, that was much better...

Also if you have some short sample file where this error
appers - you might send it to me - but I assume
that replacement with mp3lib would be a better choice here -
but I'm a bit scared of the code which is in this library...

It's usually good idea to compile with   -g 
so if you have time please recompile with just default options
and check for this again

  

debian strips per default ;), but using 20020426 with -g:
