Apparently QObject __init__ method does not call super to allow cooperative multiple inheritance as suggested in https://rhettinger.wordpress.com/2011/05/26/super-considered-super/

The script attached allows to reproduce the problem and it works with PyQt5.

I am not 100% sure whether this is a bug or intended behavior.
