try ../wp-admin/admin.php?page=bp-component-setup and save the settings again? it’s right on ‘takeoff’ ~ bp-core-catchuri.php #20 ~ bp_core_set_uri_globals() $current_component ~ all the urls depend on it and it looks like it fails if the root_blog is not the current_blog ID? sitewide activation? Not running BP on the root? I don’t know.. do you have a any other unique configuration going on?
