Trac should display LoginForm for not loged user's instead Error: Forbidden

It's very confusedly (special for new users) when the first what He see is error:
Error: Forbidden WIKI_VIEW privileges are required to perform this operation on WikiStart
Simple catching this error and checking: "User is logged or not" could create much more comfortable environment to work.
