If you are logged out, and press the Notifications button, it hangs

(Bug, To be Fixed , Priority: High, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Summary: That is, if I was logged in in this window, so the UI thinks I'm logged in, but I've either timed out or logged out in another window, I can still press the button. It fails silently; it should give an appropriate "you aren't logged in" error, and a button to log in.
