Which Vala tripped Gollum?

I've often considered this curse to perhaps be partly the Ring and partly Frodo speaking. I can't believe I forgot this, but actually one of the most convincing theories I've heard on this subject (although I can't recall where) was that Gollum fell because the Ring was still obeying the curse - because, despite the digit being severed, it was still on Frodo's finger (although he was, of course, not actually wearing it when the curse was uttered).

I any event I do like the theory that the Ring accidentally destroyed itself.
