getUnauthorizedURL is already using restrictedTraverse. This only fails 
because it starts from self instead of the parent (=portal root) and the 
login form is usually not registered for the cookie crumbler.

And it tries to call absolute_url(). Views don't have that method.


An other approach would be to look up the URLs in the Actions tool. The 
login URL is already specified in the 'user/login' Action, an invisible 
logged_out Action could be added. Long time ago the cookie crumbler had 
a stand alone version, so there are no dependencies on other tools. But 
now I would prefer to avoid redundant settings.
