you probably only need this:
(add-hook 'org-mode-hook (lambda ()
(add-to-list 'after-change-functions 'update-last-edited)))
and not this:
(add-to-list 'after-change-functions 'update-last-edited)
I guess that this last line could be causing an issue in buffers like
*Messages* which change a lot, especially during startup.
