This reminds me of something I ran into a few years ago wrt. the
attribute on exceptions. Namely, that instances of built-in exceptions
do not have a __module__ attribute, but instance of user exceptions do
-- a change which appeared in Python 2.5:


I had a use case, using ZSI to provide a SOAP interface, where being
able to get the __module__ and __name__ was needed (to serialize into a
SOAP "fault" message).

I worked around the issue by referencing the __class__ (as the other
replier mentioned). But, I didn't receive any responses then, so I think
not a lot of attention was put into these type of attributes on exceptions.
