[PyQt] why do closeEvent and destroyed slot not get called on accepting PyQt4 QDialog?

that was exactly the penny drop I was missing!

Lessons learned: 
1. Don't hook handler for destroyed signal onto the object being destroyed.
(seems obvious in retrospect)
2. QDialog.accept() does not fire closeEvent, even though it does get
destroyed - bug or documentation is misleading IMHO
3. The different syntax for hooking up to the signal - much simpler and more

Now I can get rid of the sip.isdeleted(obj) workaround in my actual code,

Many thanks!
