AIM messages couldn't be sent (though receiving worked). We were seeing errors
like:

self.uri, self.name = qname
exceptions.ValueError: too many values to unpack
I managed to 'fix' the problem, by changing line 762 of domish.py:
qname = name.split(" ")
to:
qname = name.replace(' ', ' ').split(" ")
Because we were seeing values of name like [note the double space]:
http://www.xmpp.org/extensions/xep-0084.html#ns-data data
which caused qname to contain more than 2 elements, later breaking the tuple
unpacking.
At this point I should warn: While this change fixed pyaimt for us I have no
understanding of the protocol and its entirely possible that my fix is totally
inappropriate.
