After following Rob's advice, I've found the problem is with the client
side.  If you send two get_user() requests, the second one sends a
garbage request to the server:

<?xml version='1.0'?>
<methodCall>
<methodName>__nonzero__</methodName>
<params>
</params>
</methodCall>

It looks like this is because we're reusing the same
xmlrpclib.ServerProxy over and over.  I'm guessing you need to use a new
one for each connection.

When I change the code to:

def setup_server():
    # global server
    # if not server:
    #     server = xmlrpclib.ServerProxy(server_url())
    return xmlrpclib.ServerProxy(server_url())

def get_user(username):
    """Get a specific user"""
    server = setup_server()
...

it works just fine.  Although the point is moot (since we're changing
the web gui) we probably didn't want to use a class variable anyway  (I
don't know if TurboGears is multi-threaded).
