Change this loop in Product.py to:

        try:
            for factory in getattr(self, id)._factories():
                factory._unregister()
        except: pass

The product is broken, so you can't get at it's factories
(or figure out that it has none, in this case.

That seems strange.

Where was the ExternalMethod you were messing with? 
What did it do?

I'd definiately like to look at it.

In the mean time, see if the code change above fixes the
problem.
