Comment 1 for bug 1244958

By the way, if someone is looking for a quick workaround, adding the following code in auth_signup.js after the if clause shown above worked for me:

 var currentUrlHash = window.location.hash;
 if(currentUrlHash.indexOf("token=") != -1 && currentUrlHash.indexOf("type=signup") != -1){
   self.set('login_mode', 'signup');
 }

It doesn't really address the problem but is functional and shouldn't bring up new unwanted problems.
