Description
I've been able to reproduce an issue already reported on the development ML using the stock 5.9.0RC build and one of my demonstrators (https://github.com/RJVB/fontweightissue-qt5):
2017-04-12 15:48:10.870 fontweightissue[34076:d07] +[NSGraphicsContext graphicsContextWithCGContext:flipped:]: unrecognized selector sent to class 0x7fff794b78f8 Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must not let any exception whatsoever propagate through Qt code. If that is not possible, in Qt 5 you must at least reimplement QCoreApplication::notify() and catch all exceptions there. 2017-04-12 15:48:10.871 fontweightissue[34076:d07] +[NSGraphicsContext

The backtrace is printed each time certain events are handled, and I notice that the "QFontDialog::getFont()" button is inoperable when built against Qt 5.9.0RC . In addition I can get a crash on exit with the following backtrace:

On 10.9 the `graphicsContextWithGraphicsPort` selector can be used instead.
