[Twisted-Python] xmlrpc ExpatError

[Justin Johnson]

Hello,

I have an xmlrpc server using twisted.web.xmlrpc.XMLRPC.  I have been
able to contect to it fine using just python's xmlrpclib on the client,
and am now switching over to use twisted on the client as well.  I'm
getting a wierd error though that I'm not sure how to track down.  Below
is are snippets of my client code, server code, and the error I'm
getting.

Any help you can provide is appreciated.
