At this point, lists/listname/pending.pck is corrupt and has to be
removed for normal stuff to proceed.

The underlying problem is new_members defines the UserDesc class to be
empty, thus when you call

mlist.AddMember(userdesc, remote="Webpage")

userdesc is not a valid UserDesc instance for AddMember which is where
things go wrong.

I think you need to do the following in your script.


from Mailman.UserDesc import UserDesc


class UserDesc: pass

It looks like that's all you need, but I haven't looked too thoroughly.
