I think meeting up with her - just one initial meeting - isn't a bad idea. It doesn't mean you've jumped right in and decided to be the best of friends with her, but it means you're willing to give her as a person (not a friend) a chance to explain herself and have a chat with you. And this gives you the perfect opportunity to voice everything you're feeling, particularly the current anxieties over the friendship. I don't think there's anything wrong with meeting up with her and even letting her know you're feeling rather suspicious and wary about the whole thing. I suppose, at the end of the day, it really comes down to how much you valued the friendship and how much it would mean to you to have her back in your life. Yeah you'll be going out on a limb and potentially putting yourself out there to be hurt again, but for a whole year to have passed and for her to want to meet with you and want a chat, it perhaps shows that there's still something of that friendship there. Perhaps not, of course, and that has to be your call.
One meeting wouldn't be too hard though, I imagine? Even if nothing comes of it, even if you can't rebuild that friendship, you'll have had that opportunity to talk about the things on your mind and to listen to what's on hers. Things might never be the same again (I know the feeling, I've been in a similar situation) but things can be worked on and a friendship can still come through this. If you want it. If you think she's being sincere. And, I suppose, the only way to know this (or, at least, come closer to knowing this) would be to maybe have lunch with her one day or something and talk things out.
One thing though - you know how badly things turned out a year ago, and this'll instinctively put you on your guard. This is a probably a good thing in that I don't think you'll invest too many feelings too fast. Take it slow, don't go diving in (not that I imagine you would anyway) and if something comes of it, great! If not, well, you'll not have put your heart and soul into it and, sure it'll be disappointing, but at least you'll know for sure that she's someone you need to leave in your past. If any of that made any sense at all!
Best of luck, whatever happens.
