[BUG] [new exporter] \cite and \ref in odt export

[Andreas Leha <andreas.leha@med.uni-goettingen.de>]

Hi all,

I experience problems when using \ref and \cite in documents, and then
exporting to odt.

I can replace the \ref{uuu} with [[uuu]] (breaking compatibility with
the legacy exporter), but how would I replace \cite?

My only 'solution' momentarily is to export with #+OPTIONS: LaTeX:nil


I guess this is a bug?

Regards,
Andreas

PS:
Here follows an example:

Use this bib-file:

,----[ literature.bib ]
| @article{schulte:2012,
|   author =	 "Eric Schulte and Dan Davison and Thomas Dye and
|                   Carsten Dominik",
|   title =	 "A Multi-Language Computing Environment for Literate
|                   Programming and Reproducible Research",
|   journal =	 "Journal of Statistical Software",
|   volume =	 "46",
|   number =	 "3",
|   pages =	 "1--24",
|   day =	 "25",
|   month =	 "1",
|   year =	 "2012",
|   CODEN =	 "JSSOBK",
|   ISSN =	 "1548-7660",
|   bibdate =	 "2011-10-03",
|   URL =	 "http://www.jstatsoft.org/v46/i03",
|   accepted =	 "2011-10-03",
|   acknowledgement ="",
|   keywords =	 "",
|   submitted =	 "2010-12-22",
| }
`----

When I try to export this file to odt:

,----
| #+TITLE: Citations in non-LaTeX 
| 
| 
| * Related Work...
| can be found in \cite{schulte:2012}.
| 
| 
|

| #+LATEX_HEADER: \bibliography{literature}
| #+LATEX_HEADER: \setlength{\bibhang}{1em}
| #+LATEX_HEADER: \usepackage{hyperref}
`----

I get this backtrace:
