content/browse gives a fatal error when user isn't logged in

Hi,

For example http://www.idtgv.com/content/browseurl (but in fact any eZ website)

It's not completely a bug and not completely a feature...

In fact when an anonymous user goes on /content/browse, the latter should be rejected of course.
But in a clean way

Maybe should be interesting to test is a user is logged, and if not just show a clean eZ template error (that could be overridden)

Thanks
