Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

I observe a strange interaction between whitespace-mode and org-mode
if org-ellipsis is set.

Whenever I use whitespace-toggle-options for customizing
whitespace-mode in a buffer, all org-mode buffers are effected.
Probably their display table is overwritten which only has effect if
org-ellipsis is set?

Steps to reproduce:

* Start emacs as follows (no local init file, start attached minimal
  init file, open two small org-files, also attached):

  $ emacs -q -l init.test.el test1.org test2.org

* Hit F10 in one org-mode buffer once.

* Look at other org-mode buffer to see that spaces are visualized via a
  centered dot.

What *is* happening:

* Other buffers are effected by a supposedly local action (display
  table?).

What *should* be happening:

* No change to other buffers should occur.

I'm not entirely convinced that org-mode is to blame here ...
