Use the advanced event editor (Shift+Ctrl+double click) to do something
evil to an event, like deleting the "untupledcount" property. (Whatever
that is.)
Rosegarden throws an exception out of src/base/Event.h and Qt complains
that throwing exceptions from an event handler is illegal.
That's tricky. I took a brief look and came away scratching my head on
this one.
Fortunately it only happens while using an especially grizzly and
dangerous hacker feature nobody will ever discover by accident. Or at
least so far that's the only time I've managed to follow that particular
little pathway.
(On the broader issue, I can't find anything in Rosegarden that makes me
think we handle importing triplets from MIDI correctly. I'm dealing
with triplets that aren't triplets, with all kinds of superfluous and
incorrect properties. I despair of fixing it short of a marathon
session hand hacking the XML. Blah.)

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.
