#836: Can't raise exceptions over XMLRPC

---------------------------+----------------------------------------------- -
Hey guys... there seems to be a bug when trying to raise an exception
across XMLRPC (this has worked for me before, not sure when it crept up).
Since it dies on the server side because '''!TypeError: on_error() takes
no arguments (1 given)''' this results in a '''!ProtocolError:
<!ProtocolError for host:8080/api/: 500 Internal Server Error>''' on the
client side. It's probably a pretty trivial fix for you who know what's
going on; I've looked through the code but couldn't figure it out.
