[PyQt] Simple usage of QListView seems to leak memory in PyQt 3.18.1

[Nahuel Greco]

Note, doing:

for i in range(self.list.childCount()):
        i = self.list.firstChild()
        self.list.takeItem(i)
        del i

instead of self.list.clear(), also leaks. Maybe a bug in SIP?

Saludos,
Nahuel Greco.
