Reopen Issue

When attempting to login to a SAML SP on F22 Alpha (which has python-cherrypy-3.5.0), a 500 error will be encountered on Ipsilon (using 0.4.0). Turning on debug logging shows this:

I believe that this is due to the following issue, which didn't exist in cherrypy versions < 3.3.0 (F21 is on 3.2.x):

This issue ticket was originally removed from the tracker as it clashed with the pull request.
See upstream ticket for migration details.
