While this is certainly true in general, I'd say that sip goes to great length in order to avoid that kind of crash by carefully observing who owns what. It is aware of the parent-child memory management of Qt. A python program should never be able to cause a crash. Is there any place in PyQt where the Python code has to keep references to keep the program going?
