Redirecting to Eitan, since this is probably in his bucket, either another regression from bug 686400, or one from fixing fallout of this. I haven't seen this myself, though.

This is actually the same as bug 1578185. This particular overload of MoveChild got renamed to RelocateChild in bug 1578416.
