bug#16738: Errors while resizing vertically

[E Sabof]

Another one without a clear recipe. I am using the following function on a 
fairly regular basis:

(defun es-maximize-window-vertically (&optional window)
    (interactive)
    (cl-callf window-normalize-window window)
    (unless (eq window (frame-root-window))
      (window-resize window (window-max-delta window))))

In combination with:

(setq window-min-height 1)

Sometimes it causes errors such as the ones below. In this state a) I can't 
resize any windows, using the above function. b) I can still resize using the 
mouse. c) Once I do, I usually can resize once with this function, but then I 
get a similar error again.
