MultipartPostHandler uses mimetools.choose_boundary; it relies on 
socket.gethostbyname returning a sensible result for your machine. 
But sometimes it fails: 
http://mail.python.org/pipermail/python-list/2003-October/232722.html
It may be a bug in Python, or in the sockets implementation, or 
somewhere. Anyway, choose_boundary() should be robust enough to catch 
the possible exception and act accordingly, I think.

In the meantime, you may put this near the top of your script:

mimetools._prefix = "some-random-string-you-like"
