OpenID login problem (w/ Yahoo ID)

[danbri]

I tried the openid login option with the Memcached site, using 'danbri.org' which is wired up to my Yahoo ID. "Click "Agree" to sign into contributing.appspot.com using your Yahoo! ID." Yahoo asked me to agree to the login, then bounced me back to a http://contributing.appspot.com/s/finish?blahblahblah ...which seems to be a completely blank page (ie. view-src in Chrome shows nothing).

Debugging OpenID is a thankless task, but I thought I'd mention this at least. Let me know if I can provide more useful detail.
