I've been playing with this but can't get to the root of the problem. The 
crash is happening in the QApplication dtor and I'm beginning to suspect that 
it is a Qt bug.

I'd be interested in playing with your C++ version. You might try explicitly 
deleting the button then the QApplication just before returning from main(). 
This would more closely mimic what PyQt is doing.
