Thanks to Matthew for the info about texi2dvi!

You're welcome. It was needed for me as well...

Tested on the document for which I experienced the troubles in the first place
(because my TOC was more than one page long). Works perfect!

Only one comment, after reading your code in org-latex.el: if there is no
texi2dvi executable, please run pdflatex 3 times, as this is the right number
to get the TOC in sync' with the document, when it's more than one page long
(at least, in my above case, with a couple of org-babel sql source blocks).
