[PyQt] Segfault in QMenu.addAction when parent widget is deleted.

Hi all, I wanted to share this small example program that will segfault.

The newest PyQt I have been able to test it with PyQt 4.10 / Qt 4.8.4, so I
don't know if it has been fixed already.

In boils down to trying to add a new action to a submenu of a menu attached
to a widget that has been deleted. We're having this problem due to some
asynchronous RPC and getting results back after a user has caused the
widget to go away.

If anyone can try this in a newer PyQt to see if it still crashes, I would
appreciate it.
