Is there something I am supposed to do to the enum_ to make it work? If I try to 'dumps()' my enum I still get the exception I included in my earlier email. Funny thing, dumps-ing it with cPickle just gets the exception, while dumps-ing it with regular pickle also produces a crash from within the bowels of Python25.dll.

Ralf, did you receive stuff from Shashank back then? (Or did you wait until today with committing the fix?)
