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 am exporting a large table from org to pdf via LaTeX. The meaning of
some of the column headers are to be explained in footnotes. The table
spans more than one page, so continuation headers are generated using
longtabu. These continuation headers mangle with the footnote numbering
as can be seen in this example:

# -*- mode: org -*-
#+STARTUP: showall
#+LaTeX_CLASS_OPTIONS: [a5paper]
#+LATEX_HEADER: \usepackage[T1]{fontenc}
#+LATEX_HEADER: \usepackage[utf8x]{inputenc}
#+LATEX_HEADER: \usepackage{tabu}
#+TITLE: Multi page table test

* Multi page table

  #+ATTR_LATEX: :environment longtabu

[fn:test] becomes [1] in the first, and [2] in the continuation headers,
but [2] links to the content of [fn:test2], which becomes a reference
without target.
