Navigating from a project bug list back to all bugs is difficult.

If for example I'm at Launchpad Itself and I'd like to go back to all project bugs page (bugs.launchpad.net) there doesn't appear to be an easy way. Should the bread crumbs show Home->Bugs->Launchpad Itself? Very confusing. Works well if you only work with one project I guess but not friendly at all to the majority of visitors who are possibly interested in a group of projects or just bug reporting.
