    Bug 664885 - Open 'Document History' --> always a additional history tab appears
    
    Really find a *widget* in gimp_dialog_factory_find_widget(), don't
    just return the first found session info's widget. It's perfectly fine
    for a session info to have a NULL widget, if that dialog is not
    currently open.
