[Bastien Nocera <hadess src gnome org>]

commit 28f1b87e51492147e9f8653139407707fb074761

    Ref TotemScreensaver so it's still valid in the cb
    
    Especially on exit, we need to keep our own reference of the
    screensaver object, or it might disappear by the time we
    receive the callback from GDBus.
