Clicking 'list my groups' when browsing 'My memberships' causes the breadcrumb location to disappear when you then click 'Explore

Report from Chris:

When I go to "my memberships", and "list my groups", then click on "explore", I don't see the current location breadcrumbs anymore... This seems like an important issue. Thoughts? Btw, if I go back to "my memberships", and click "show folders and groups", then the breadcrumbs are back on...
