Interestingly and as reported, it does not happen when downgrading to ESS 13.09 (but as this was handled as an org-mode problem so far I decided to keep it on this list).

Yes, I can reproduce with emacs 24.3.1, org 8..2.3, and ess 14.09 on
Archlinux, but only if I don't start the R session first. If I do 'M-x
R' to manually start an R process it works fine, but if there is no R
process already running I get 'Error: could not find function
".ess.eval"'
