23481	Cannot view Trac tickets when logged in through GitHub	Kevin Brown	nobody	"==== How to Reproduce ====

1. Remove the email from your Trac settings.
2. Log out.
3. Log in using the GitHub login.
4. View any ticket.
5. Trac gives an Internal Server Error.

If you set an email in your settings, this error disappears and tickets can be viewed. If you remove the email from your settings, and do not go through the login cycle again, this error will not appear. This error only occurs when you log into Trac and the email was not previously set.
