python-yadis or python-openid I really don't know which; version 1.1.0.
python version Python 2.7.3
Ran 80 tests in 0.036s
My impression this is triggered by a change in python2.7 earlier this year.
Await your verdict.
Thank you for not looking into this issue in 3 years dear Open ID developers ;) We've removed this test so that the test suite can pass.
Please close this bug.
