emacs -Q,  if eval  (mouse-avoidance-mode 'animate) the problem still exit

I did some debug, found that in the following function,  `posh-at-point' will 
return nil .

(defun mouse-avoidance-point-position ()
  "Return the position of point as (FRAME X . Y).
Analogous to `mouse-position'."
  (let ((edges (window-inside-edges))
        (x-y (posn-x-y (posn-at-point))))
    (cons (selected-frame)
          (cons (+ (car edges)
                   (/ (car x-y) (frame-char-width)))
                (+ (car (cdr edges))
                   (/ (cdr x-y) (frame-char-height)))))))

I'm not sure it's the bug of org-mode or emacs.
