"Attribute Doesnt Exist" ... but.... it does :-s

Well thanks for the response, I followed your advice and chopped out all the
crap from my class, right down to the bare __init__ and the setter method,
however, the problem continued to persist.
However, Robert mentioned something about unindented lines which got me
thinking so I deleted my tab indents on that method and replaces them with
standard space-bar indents and it appears to have cured the problem.
Usually my Eclipse IDE throws up an error about this but for some reason
decided not too this time around, what a PITA.
Thanks for the ideas guys, I appreciate it.

I don't get this error if I run your code. Maybe the irrelevant code
causes the error: my guess is that there's a parenthesis mismatch or an
Btw, calls to set_pending_list will fail since the name "message_list"
is not defined in its scope. Please follow Chris Mellon's advice.
