After she was kicked out of the party, one can find her at one of three places (Beregost, Friendly Arm Inn, somewhere else). If one enters into the area where she is, she directly starts to talk. Under normal circumstances, she should only start her "rejoin"-dialogue if one talks with her. What is even worse, if one doesn't let her rejoin, but tells her to stay here, the "rejoin"-dialoge directly fires again. So one has to either get her into th party or send her to one of the other two places to go go on with the game. Lollorians fix is helpful, but as far as I understand it, it doesn't fix the problem, but gives one simply some time to go on with the game before she starts talking again...
