Just to follow up on this -- QObjectCleanupHandler connects to the destroyed signal in order to get notification of object deletion. PySide already has code to do this, but it's disabled. I think the problem is one of ordering: there's no guarantee that that the destroyed signal handler that invalidates a wrapper won't be followed by another destroyed signal handler that calls back into python code that needs to access the object. My proposed solution gets around this by using a property which isn't cleared until all of the destroyed handlers are invoked. It's a bit of a hack to do it this way, but I think it's better than the alternatives. I thought I saw something that Qt 5 may provide better support for bindings, but we need to use Qt 4 for now.
