I think thats normal (Phil will know for sure). I don't know sip
internals, but I think what happens is that the refcount for the
Python-Wrapped QMenu is not incremented in setContextMenu, which is
quite natural as its a C++ function from Qt not knowing anything about
Python. Keeping a reference to the object yourself is the proper
solution here.


Tonight you will pay the wages of sin; Don't forget to leave a tip.
