Simple source block breaks LaTeX export

Simple source block breaks LaTeX export

[Daniel E. Doherty]

If I try to export the following org file to LaTeX, I get a stringp
violation.

==================================
* Hello
#+begin_src ruby
  $f = []
  $f[0] = $f[1] = 1
#+end_src
==================================

Here is the traceback:

Any ideas what may be causing it?  Looks like something going wrong with
org-export-footnotes-seen, but that's as much as I can tell.

What version? It works fine with Org-mode version 7.7 (release_7.7.624.gda56)
which is not quite the latest, but it's close. I also took the opportunity
to pull latest (Org-mode version 7.8.02 (release_7.8.02.2.g490d6a)) and it
works fine there too.

This was fixed shortly thereafter. You have to either upgrade or cherry-pick
the fix. The relevant commit is

Thanks, Nick.  That was it alright.  Having the package manage in Emacs
24 makes this kind of fix really easy.
