[new exporter] problems exporting mathmode to LaTeX

[Thomas Holst <thomas.holst@de.bosch.com>]

Hi,

forgive me if I am nagging :-). One of my collegues and myself want to
switch to new exporter. While testing the new exporter on our existing
org-files we encounter these problems.

So here is the next one:
#+BEGIN_SRC org
  160\(^\circ\}\nbsp{}C
  -11^{\circ}\nbsp{}C
#+END_SRC

With the old exporter this becomes:
#+BEGIN_SRC latex
  160\(^\circ\)~C
  -11$^{\circ}$~C
#+END_SRC
in LaTeX. Which looks well in pdf.

With the new exporter it becomes:
#+BEGIN_SRC latex
  160\(^\circ\)~C
  -11$^{\mathrm{\^{}}}$~C
#+END_SRC
in LaTeX. Where the second construct obviously is not what is expected
and looks totaly wrong in pdf.

Again with emacs -Q
(emacs-version)
"GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
 of 2011-09-19 on 3249CTO"

(org-version)
Org-mode version 7.8.11
