Any of the places I take her, nothing. Any fix?

I had some issues with her not initiating any conversation, though she did make some verbal comments late (IE: talking about the plasma weapons from Silver Rush after we left and almost got to Camp McCarran). Opening the companion wheel and talking to her directly did work at McCarran, although I think the bug there may have been from having ED-E auto-initiate conversation at the same spot and just happen to be closer.
