[Bastien Nocera <hadess src gnome org>]

commit 07e11de11a9f84209b31ebffdeec4983f91b9dae

    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.
