I hope somebody recognizes that message. If not, here are som suggestions:


#+NAME: alpha
#+BEGIN_SRC emacs-lisp
"abc"
#+END_SRC

produces

#+RESULTS: alpha
: abc

when you run `org-babel-execute-src-block'. Does changing "emacs-lisp"
to "R" and running again erase the result or fail to insert it if
you first run `org-babel-remove-result'?

You have already checked that C-c C-v C-i for both versions yields
identical results, right?

If so, I'd instrument `org-babel-execute-src-block', execute and then
type 'h' just before the `(org-babel-insert-result ... ' --- a couple
of lines from the bottom --- once you enter edebug. Then `e' and
`results' to see that it is what you suppose it should be. Then step
thru the next few lines to insert the result. Then check the buffer to
see what happened. If no result was inserted, then I'd instrument
`org-babel-insert-result' and work from there.

HTH,

Chuck

p.s. You are not trying to export this and depending on the exporter
to run babel, right? Because there is another trick lying in wait...
