Setting it as a class level attribute seems to suppress it:
>>> class TestError(Exception):
... message = ""
... def __init__(self, msg):
... self.message = msg
Since it's a string and passed by value I think this would work. I'll
open up a ticket if one's not already.

So yes, we need to keep it; it doesn't mean the same thing as Python's earlier 'message' attribute on Exception. If we can simply squash the warning that would be best.
