I was aware that my "emacs -Q" test was done against org-mode version 8.2.x. However, I use the latest org-mode from Git everyday. For example, the version I'm currently using is (from M-x org-version): "Org-mode version 8.3beta (release_8.3beta-509-g86ec0a.dirty @ /usr/local/share/emacs/site-lisp/org/)". So apparently the problem had never been addressed. > Meanwhile, I suggest to insert some subsections in your file. What do you mean by "insert some subsections"?
