[Orgmode] Error when exporting as Latex

[Paul Mead]

Hi

I've only just spotted this error as I don't use the Latex export very
often. When I export as Latex either to file or buffer, I get the
following error:

org-export-latex-lists: Wrong number of arguments: #[(list)
"\"" [list org-list-to-generic (:splicep nil :ostart
"\\begin{enumerate}" :oend "\\end{enumerate}" :ustart "\\begin{itemize}"
:uend "\\end{itemize}" ...)] 3
("c:/bin/emacs-22.3/lisp/textmodes/org-export-latex.elc" . 39820)], 2

I've tested this on a file which is unchanged from when I last
successfully exported it, many org versions ago.

Org-mode version 6.28trans
GNU Emacs 22.3.1 (i386-mingw-nt5.1.2600) of 2008-09-06 on SOFT-MJASON

Any ideas?

Thanks, Paul
