I used exactly the plugs @Airhead linked to to hang the twinslot rails in my living room. Some blown plaster over brick. I followed another bit of advice I saw online which was to drill the holes a little deeper than required and fill them with adhesive (No More Nails type stuff), smush the plugs in, clean off the adhesive that squeezed out and let set overnight before hanging.
Hasn't fallen down yet. Also, god love the person who has to deal with removing the plugs in future (probably me, in which case "fuck you, past stevo_com!").
