I've fixed this (and a similar problem with `kill-buffer-hook') in the trunk.

Best regards, Michael.

It seems that autorevert.el:316 adds a lambda to `find-file-hook':

(add-hook 'find-file-hook
	  (lambda ()
	    (setq-local auto-revert-tail-pos
                        (nth 7 (file-attributes buffer-file-name)))))

It's bad practice to add lambdas to hooks as it makes it harder to remove them.
We should use a named function instead.
