When I click on a link on a build failed email and I haven't yet logged into
Hudson, I get an error page. There is no stack trace in the hudson log. I just a
page that says
Status Code: 404
Exception:
Stacktrace:

I should instead get a login page as this project doesn't allow read access to
anonymous.
