I get "Error: could not find function ".ess.eval"" when inside an R code
block with :session *R* but not without :session *R*.

release_8.3beta-427-g942eb6) and the current development version of ESS
(the same happens for ESS 14.09). 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"'
