    pathbar: keep a ref to the GFile while updating the path
    
    When desktop-is-home-dir changes, we force a re-layout of all the
    buttons, which in turn unrefs the passed-in GFile, as the ref would
    belong to an old button. Fix this by assuming a ref while calling
    nautilus_path_bar_update_path().
