Is there something in the nature of pyobjc objects that makes them confuse dockets?

Not sure if the class repr at the top of the traceback is relevant, but if it is this might be due to doctest trying to test some PyObjC classes.

Iíve done some investigation, and this likely is doctest being confused by a bug in PyObjC: some of the types created by PyObjC donít have a __module__ attribute due to a misunderstanding of the heaptype protocol on my part. Iíll fix this for a future release.
