I wonder if something about the MIDI subscription from Rosegarden is confusing Ardour. I probably have to bow out here -- it doesn't look like the problem's in Rosegarden, and I don't know enough about Ardour to help out any further. You could probably do with getting a stack trace from gdb or whatever, but I'm not sure whether you'll manage that with the Debian package of Ardour or whether you'd have to build your own with debug symbols.
