It depends on the specific library used. Generally, the type of the
exception, sometimes in conjunction with the error message, will tell
you what went wrong. In this case, the xmlrpclib.Fault exception
represents all XML-RPC Faults, and there are faultCode and faultString
attributes to figure out where it went wrong. See also the xmlrpclib
documentation (docs are your friend!)
