I'm guessing this a problem either in urllib2 or the bzrlib wrappers. 
launchpad-login, which uses the bzrlib HTTP transport (i.e. NOT 
xmlrpclib) to request the sshkeys URL, fails unless I modify 
launchpad/account.py to specify port 443 in LAUNCHPAD_BASE.

I guess I should go poking around in the wrappers and urllib2.
