The error can be reproduced with
Python 3.1.1+ (r311:74480, Nov 2 2009, 15:45:00)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import logging
>>> from logging.handlers import SysLogHandler
>>> handler = SysLogHandler()
>>> logger = logging.getLogger()
>>> logger.addHandler(handler)
>>> logger.critical("yadda")
Traceback (most recent call last):
File "/usr/lib/python3.1/logging/handlers.py", line 785, in emit
self.socket.sendto(msg, self.address)
TypeError: sendto() takes exactly 3 arguments (2 given)
This is is a known bug, see http://bugs.python.org/issue7077
