I think the problem is that the code block does not "see" the previously
produced #RESULTS: (because of the intervening #CAPTION:), so when run
again it adds another #RESULTS: section.

I think the best way to deal with problems like this is to name your code blocks
(and results blocks).

Try the following:

--8<---------------cut here---------------start------------->8---
#+name: foo
#+begin_src R :exports both :results graphics :file img.pdf
hist(rnorm(100))
#+end_src

#+CAPTION: Some description
#+RESULTS: foo
[[file:img.pdf]]
--8<---------------cut here---------------end--------------->8---

Does it solve the problem?
