Ater the " processAsynchronousEvents" and "Successfully opened document" messages the system slows to a halt and my hd led stays on, most probably because I have a new mother board with only one pata slot and a primitive pata drive. To reproduce, open attached bug-599517_unicornis.rg then import studio from bug-599517_studio.rg and at least my system survived but Michel reckons his firefox crashed from out of memory, mine survived, maybe because of gdb, and I got this message :- [sequencer] processMappedEvent: Have 66 events in async out queue
RosegardenDocument::openDocument: Successfully opened document

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.

Michel is still using qt 4.5.3 but I'm on 4.6.2 atm so maybe that saved
me from more catastrophe.
