Alright, by adding the lines I had to remove from Reunion.xml to the "Hello World" example from the MusicXML tutorial, I managed to reproduce this traceback with a much smaller example. Of course, I don't know enough MusicXML to tell if the result is supposed to make sense or not; it's kind of nonsensical to add a brace to a single-staff system though it does validate and it does import cleanly into MuseScore (though it's probably just being lenient). Also, I don't think that's what musicxml2ly is struggling with; it crashes for the double-staffed Reunion file as well.
