When talking to an Apache XML-RPC library based application via python 2.6.5 xmlrpclib, I get this exception:
Traceback (most recent call last):
  File "prb.py", line 4, in <module>
    proxy.catv.getEndpointIdByIp('1.1.1.1')

    self._parser.Parse(data, 0)

    return f(self, join(self._data, ""))
  File "/tmp/Python-2.6.5/Lib/xmlrpclib.py", line 935, in end_struct
    dict[_stringify(items[i])] = items[i+1]
IndexError: list index out of range

The exception is caused by the XML response, which includes a value with "ex:i8" type. According to this: http://ws.apache.org/xmlrpc/types.html, there are a lot more types, which are not understood by python's xmlrpclib.

It's easy to fix the above by adding "ex:i8" to the list of end_int dispatcher:
    def end_int(self, data):
        self.append(int(data))
        self._value = 0
    dispatch["i4"] = end_int
    dispatch["i8"] = end_int
    dispatch["ex:i8"] = end_int
    dispatch["int"] = end_int

This makes the error disappear (and the program to work).
Of course, it would be nice to support all other types as well (in both directions).
