OK, thanks. It had to be something in my init.

I have (defun org-mode-reftex-setup () ... ) from

http://www.mfasold.net/blog/2009/02/using-emacs-org-mode-to-draft-papers/

in my init.

It turns out that

   (re-search-forward "^[^%]*\\\\usepackage.*{biblatex}" nil t))

in reftex-using-biblatex-p is the culprit.

So, the ECM is to save a file like that decribed above without the *.org 
extension.

Open it (in fundamental mode) and issue

M-: (re-search-forward "^[^%]*\\\\usepackage.*{biblatex}" nil t))

and get

eval: Stack overflow in regexp matcher

So, maybe this is not an org-mode issue. ??


HTH,
