Hi Nick,

Thanks for the patch, sadly I rely on labels in my other latex exports.
For now I'm just using the following little elisp function.

--8<---------------cut here---------------start------------->8---
(defun schulte/clean-beamer ()
  "remove the \label{sec} headers from latex Beamer documents
that have been exported by org."
  (interactive)
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward "^\\\\label{" nil t)
      (move-beginning-of-line nil)
      (delete-region (point) (save-excursion (forward-line 1) (point))))))
--8<---------------cut here---------------end--------------->8---

Thanks -- Eric
