[Orgmode] Bug: Footnotes in combination with LaTeX fragments is broken in latest trunk

[Bjørn Arild Mæland]

Hi,

In the latest trunk version of org-mode
(4cbedbff1adf22e2018baf5c674b32a91c68007e) I get an error when I
export the following org file to pdf:
,----
| #+LATEX_HEADER: \usepackage{acronym}
| #+LATEX_HEADER: \acrodef{SRILM}{The SRI Language Modeling Toolkit}
|
| * Test
| \ac{SRILM} [fn:srilm]
|
| [fn:srilm] http://www.speech.sri.com/projects/srilm/
`____

The error is as follows: "org-footnote-normalize: Invalid use of `\'
in replacement text".

This works fine in 6.32b, however.
