This was a year ago, but I can still reproduce this on the current
trunk. Here's an even easier variation of the recipe:
(progn
(blink-cursor-mode -1)
(global-eldoc-mode -1)
(defun myfun ()
(interactive)
(tool-bar-add-item "redo" 'undo-redo 'undo-redo))
(global-set-key [f5] 'myfun))
And then M-: (garbage-collect) makes the tool bar update.
However! The garbage-collect in itself isn't sufficient to trigger it.
With this variation:
(progn
(blink-cursor-mode -1)
(global-eldoc-mode -1)
(tool-bar-add-item "redo" 'undo-redo 'undo-redo)
(global-set-key [f5] (lambda () (interactive) (garbage-collect))))
pressing <f5> does not make the icon appear.

Very mysterious.
