I don't know what the deal was, but the initial dialog when you free her is all screwed up. Everything seems normal, but you never know. I tried to do a screen capture, but it doesn't seem to work. She was talking about how she wasn't going to rescue me and something about Jaheira or Kaleed, I forget, but I have neither in my party and the context didn't sound like the dialog was supposed to be there. Also, it gave me the description of the spell abjuration as one of the choices to say to her.
I did do the Nashkel Mines before I went to the carnival. I don't know if that's what messed it up, since the intent seems to be you go to the carnival before going to the mines.
Is this going to affect anything in the future? I could upload my save if you never seen anything like it before.
