PyPI XML-RPC errors

gistfile1.sh

Fails on Python 2.6 with http:

$ python2.6 releases.py http
Traceback (most recent call last):

    print xmlrpclib.ServerProxy('%s://pypi.python.org/pypi' % protocol).package_releases('roundup')

But works in 2.6 with https, or Python 2.7 on either protocol:

$ python2.6 releases.py https
['1.4.21']
$ python2.7 releases.py http
['1.4.21']
$ python2.7 releases.py https
['1.4.21']

releases.py

import sys
import xmlrpclib

protocol = sys.argv[1]
client = xmlrpclib.ServerProxy('%s://pypi.python.org/pypi' % protocol)
print client.package_releases('roundup')

This presented itself in my project by breaking the Tox bootstrap script from here:

http://testrun.org/tox/latest//example/jenkins.html?highlight=toxbootstrap

This was working within the last few days, but today it was broken:
