So tonight I was playing around on the site and I noticed I somehow was able to triggered this exception. If it didn't appear in the logs, it would have gone completely unnoticed. Now I will say I logged in using facebook which uses oauth and at some point during the login process, this exception was triggered. Here's the exception in it's entirety.
