I commented the above in my `.emacs' file and restarted Emacs.

Yes, I'll do that now... In fact, I implemented this, years ago, for "easily"
attaching documents to emails.


>> When looking for the current value of that variable

I now have:

--8<---------------cut here---------------start------------->8---
default-directory is a variable defined in `C source code'.
Its value is 
"/home/sva/Projects/Insurance/Acme/docs/operations-manual/"
Local in buffer Upload_documentation.tex; global value is nil

  Automatically becomes buffer-local when set in any fashion.
  This variable is safe as a file local variable if its value
  satisfies the predicate `stringp'.

Documentation:
Name of default directory of current buffer.  Should end with slash.
To interactively change the default directory, use command `cd'.
--8<---------------cut here---------------end--------------->8---

from both the Org file and the TeX file. Correct, thus.

Though, I have exactly the same problem as yesterday: only the TeX file is
produced locally when `C-c C-e d', and all the other files (.aux, .log and the
.png from Ditaa) are stored in `~/'.

Ununderstandable...

Best regards,
  Seb
