I'm not sure if the key signatures had anything to do with it, but the steps were roughly:

- new score
- add a few notes
- add a key signature
- add another key signature
- undo
- undo
- CRASH

See attached crash trace.

Hi zscore

The crash log has nothing to do with key signature. It's a low level crash in Qt paint engine code called by our style.
