I'm the type that always likes to bring our hostess (family or friends) either a small gift or bottle of wine, so I understand your SIL way of thinking. I would probably just accept what ever she brings graciously, saying something like ...."thank you so much, but you know this wasn't necessary as I didn't expect anyone to bring something". Chances are, if others are like members in my family, they will bring something anyway too, so your SIL won't be the only one, just the one to tell you ahead of time.
Could be worse....hopefully she won't be like my sister and bring a frozen ham to Christmas dinner (she was "down" for the ham that year).
