I've had her dead on the beach but never had that happen. So far, the only weird dialogue was my character saying to Astarion something about never sleeping in a forest before, but we were in the Dank Crypt mini camp, not the forest. Oh, and Astarion revealed to me stuff about Cazador and being a vamp BEFORE he tried to bite me.
So, glitchy yes. However, I don't think it's game breaking and would need 10 years to fix.
