 This looks like a corrupt MIDI file. Ardour should probably refuse to load it. Where did you get this file from, do you know what software was used to create it?

Unfortunately I have no idea. And I agree that Ardour should either refuse to load it (probably easier) and definitely refuse to save something it cannot load.

Fixed in 6.3-307-gd3eab4e309.

The issue is that the MIDI file contains a metrum change in the middle of a bar. This is not possible in music notation and caused ardour's tempo-map to go haywire.
The meter-change is now ignored. On the upside, that change happened at the end of the given file, so for the case at hand it's not a big issue.
