intertwingly

I got a report from Bob Aman that my “blog broke”, along with the following traceback:

   assoc_type = results['assoc_type']
TypeError: unsubscriptable object

A quick search turns up nothing.

Checking Bob’s server, I find:

<link rel="openid.server" 
      href="http://sporkmonger.pip.verisignlabs.com/server/" />
<link rel="openid.delegate" 
      href="http://sporkmonger.pip.verisignlabs.com/" />

The server URI provided returns a 404, presumably as the result of a configuration error.  It seems likely that https://pip.verisignlabs.com/server was what is intended.  In any case, JanRain Python OpenId 1.2.0 responds rather poorly to this situation, and the following patch works around this bug:

Now off to report the problem: done.
