I never did that explicitly.

But, doing it does effectively solve the problem at hand.

The last time I tangled such an Org file containing `latex' code blocks
and generating (at that time) a `file.tex' was on 2014-01-13.

So did I think. Though, I had to edit `org-babel-load-languages' to
support Org installations with the latest Git version and Org
installations with the latest ELPA version:

--8<---------------cut here---------------start------------->8---
    (if (locate-library "ob-shell")     ; ob-sh renamed on Dec 13th, 2013
        (org-babel-do-load-languages
         'org-babel-load-languages
         '((R          . t)
           (awk        . t)
           (ditaa      . t)
           (dot        . t)
           (emacs-lisp . t)
           ;; (latex   . t)
           (ledger     . t)
           (org        . t)
           (shell      . t)
           (sql        . t)))
      (org-babel-do-load-languages
       'org-babel-load-languages
       '((R          . t)
         (awk        . t)
         (ditaa      . t)
         (dot        . t)
         (emacs-lisp . t)
         ;; (latex   . t)
         (ledger     . t)
         (org        . t)
         (sh         . t)
         (sql        . t))))
--8<---------------cut here---------------end--------------->8---

... and I did comment `latex', thinking that, in such cases, I should
certainly use #+begin/end_latex blocks instead.

In the file I tangled, this wasn't the case.

So, yes, I did change something, which lead to some peculiar
observation.

Thanks for putting me right on track!

Best regards,
  Seb
