------- Comment #3 from Tim-Philipp Müller  2007-04-10 11:10 UTC -------
This happens with VBR mp3 audio files, probably with both the 'mad' mp3 decoder
and fluendo's 'flump3dec' mp3 decoder.

This is really expected behaviour at the moment. In order to know the exact
length of an VBR mp3 file, GStreamer would need to scan the entire file (or at
least parts of it), something which causes as many problems as it solves (think
of files mounted on an NFS/samba share etc.), so it's a trade-off we're making
on purpose here.

We should be able to handle this better though, hence marking as enhancement
and moving to GStreamer.
