new exporter - LaTeX export setting org-export-latex-packages-alist and BUG empty source block export

Hi

I had the following in my emacs.org:

#+begin_src emacs-lisp
  (require 'org-latex)
  (setq org-export-latex-listings t)
  (add-to-list 'org-export-latex-packages-alist '("" "listings"))
  (add-to-list 'org-export-latex-packages-alist '("" "color"))
#+end_src

After upgrade of org this morning using git, the new exporter is there and I get the following
error message:

(void-variable org-export-latex-packages-alist)

I just commented them out and added

#+LATEX_HEADER: \usepackage{listings}
#+LATEX_HEADER: \usepackage{color}

to the files concerned

In addition, there seems to be a BUG:

when exporting an empty source block to LaTeX, I get the following error message:

org-babel-exp processing... [69 times]
apply: Wrong number of arguments: max, 0

I can easily replicate this with a document only containing:

* org-mode
#+begin_src emacs-lisp

#+end_src

which exports fine to html, but not LaTeX.

Cheers,

Rainer

It should be `org-latex-packages-alist', `org-latex-listings'. You also
don't need (and shouldn't) require 'org-latex. Please see:

Indeed. It should be fixed now. Thank you for reporting it.

Thanks - working now.

One observation though: I updated and compiled org while emacs was running, then reloaded it and
tried the export of the empty souce block, and the error was still there although emacs told me
that I had successfully loaded the new version.

I restarted emacs, and the export worked.

Cheers,

Rainer

I have updated `org-reload'. It should also reload back-ends. Thank you.
