I am using xmlrpclib against an internal xmlrpc server.
One of the responses returns integer values, and it raises an exception in "_stringify"
The code for _stringify is (xmlrpclib.py:180 in python2.7):
if unicode:
 def _stringify(string):
 # convert to 7-bit ascii if possible
 try:
 return string.encode("ascii")
 except UnicodeError:
 return string
else:
 def _stringify(string):
 return string
So when "unicode" is available, .encode is called on the parameter (which are the returned objects from the server) which fails for ints.
Without the unicode path it works fine, proven with the following monkey-patch:
xmlrpclib._stringify = lambda s: s
I am using the above patch as a workaround, but a fix to the library should be straightforward, simply checking for AttributeError in the except clause would solve it while retaining the existing functionality.
The traceback:
