I have a not very deep data structure. It just contains a dictionary and some lists, nothing to scary. But when I try to deepcopy it, I get bad errors (below). I've googled and found a barely related bug reported only once, so I don't really believe this is likely a python bug. Anyone seen this before? Any thoughts? >>> c=copy.deepcopy(b) Traceback (most recent call last): File "<stdin>", line 1, in ?
