The :post trick works by side-effect: org-redisplay-inline-images does
what it says and it returns the string that `message' prints in the echo
area. Unfortunately, on export, :post is processed further with the
result that the meaningless string is passed to org-babel-ref-resolve
as a reference to be resolved - with predictable results[fn:1].

I think you'd be better off with the tip that Rick Frankel posted in
the same thread:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC emacs-lisp
(add-hook 'org-babel-after-execute-hook
(lambda () (org-display-inline-images nil t)))
#+END_SRC
--8<---------------cut here---------------end--------------->8---

That's executed after you evaluate the block so it displays any
image(s) produced. And it does not interfere with export.

Footnotes:

[fn:1] Assuming 20-20 hindsight of course...
