MIDI files don't play properly: sound is different to what it should be

[turbolad]

Ubuntu 11.04 64-bit.
Totem version 2.32.0

When playing MIDI files in Ubuntu, they play totally different compared to playing the same MIDI files in Windows. The MIDI files are playing wrong. The media player then carries on running forever after the MIDI sound has been played from start to finish, but you can close Totem afterwards as it does not freeze in any way.

If you don't have any MIDI files to test this bug, the vgmusic site has many MIDI recordings of video game tunes and you can try playing them in Windows and Ubuntu. I dual-boot both Windows 7 and Ubuntu - that's how I discovered this problem.
