[O] bug in ox-koma-letter

[Thomas Holst]

Hello all,

when I try to export an subtree with koma letter I get the following
error:

  cond: Symbol's value as variable is void: with-title

This seems to be related to the following commit:

  d3196f0 * ox-koma-letter: Fix missing \begin{document}

because if I switch to the commit prior to this one (6463b6c *
ox-koma-letter: Fix typo in docstring) everything works
fine and I don't get an error.

Emacs Version: 24.3.1 on Ubuntu 12.04
org-version: most recent git

Thanks for looking into this.
