[BUG] (wrong-type-argument wholenump nil)

["Sebastien Vauban" <sva-news-D0wtAvR13HarG/iDocfnWg@public.gmane.org>]

Hello,

With a *minimal config file* and

  Org-mode version 8.0.6 (release_8.0.6-357-gf00d75 @ d:/Users/sva/Public/Repositories/org-mode/lisp/)

there is a Lisp error generated when trying to split a block of code into two
pieces through `C-c C-v C-d' (org-babel-demarcate-block).

ECM:

--8<---------------cut here---------------start------------->8---
#+begin_src sh
ls
ls
#+end_src
--8<---------------cut here---------------end--------------->8---

Steps to reproduce:

1. Put point on the second "ls" line
2. Press `C-c C-v C-d'

Backtrace:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument wholenump nil)
  make-string(nil 32)
  (let ((lang (nth 0 info)) (indent (make-string (nth 5 info) 32))) ...)
  ...
  org-babel-demarcate-block(nil)
  call-interactively(org-babel-demarcate-block nil nil)
--8<---------------cut here---------------end--------------->8---

FYI, it works in an old Org version (such as 7.9.2+, bundled with GNU Emacs
24.2.91.1).

Best regards,
  Seb
