Unauthorized review doesn't redirect properly

[marivb]

When I try to create a review for a session I can't (happens also when you submit something just after someone has completed the third review on a session), firefox gives me an error page saying:

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

Then, the first page I access on the actual site (say, I go back to the home page) will give me the actual permission error : "Você não está autorizado a acessar esta página"
