Sdl_mixer issue with a midi file

Hi,

we have a bug on the pygame issue tracker to do with sdl_mixer and a midi
file:

The midi file appears to work on the windows builds with sdl_mixer. But not
on the OSX or linux builds.

The file works if run manually with timidity on linux, but playmus.c fails.

Here is the midi file:

Any ideas?
