[O] :components part in org-publish-project-alist fails

[Julien Cubizolles]

In git master, consider the following,

--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp :tangle yes :exports none
  (setq org-publish-project-alist
        `(("latex"
           :base-directory "./"
           :publishing-directory "./"
           :publishing-function org-latex-publish-to-pdf
           :exclude ".*"
           :latex-class "article"
           :include ("test.org")
           )
           ("global" :components ("latex"))))
#+end_src

#+RESULTS:
| latex  | :base-directory | ./      | :publishing-directory | ./ | 
:publishing-function | org-latex-publish-to-pdf | :exclude | .* | :latex-class 
| article | :include | (test.org) |
| global | :components     | (latex) |                       |    |             
         |                          |          |    |              |         |  
        |            |

evaluate the source block with C-c C-c and publish the "latex" project
(C-c C-e P x latex). The publication works. However the "global" project
fails. The message in the *Org Export Process* buffer is just "nil"...

I've been using this setup for a while without any problem in the
past. The latest master from git broke it.
