I delete all top-level widgets, flush all the events
(qApp.processEvents()), and run an explicit gc.collect() pass. I
actually don't know what else to do...
I start to believe that it's a Qt problem rather than a PyQt's one; eg:
some globals somewhere in the focus code that is not reset by
QApplication's destructor and still points to some destroyed object.
I'll have a further look.
