I just ran into this bug and tried to apply the patch locally, but ran
into poblems. If the address of the PyObject* can be used, I think that
would be preferable. Consider the following:
o = QObject()
d = {}
d[o] = 1
def on_destroy():
d.pop(o)
o.destroyed.connect(on_destroy)
shiboken.delete(o)
The pop in the destroy handler will fail with a RuntimeError and even if
the RuntimeError is suppressed and a default hash value returned, the
entry in the dictionary won't be found or removed.
