I'm new to the developers' mailing list, so I hope this is the right place to post potential bugs.  I don't claim to know exactly why, but at least for certain TOC options, the LaTeX exporter produces invalid code for item titles containing footnotes.  I've attached a minimal (non)working example.

The resulting LaTeX code (also attached) uses \footnote inside \section and \paragraph macros, producing compiler errors.  A little googling turns up the following comp.text.tex usenet post https://comp.text.tex.narkive.com/lkZWQYaS/using-footnotes-in-paragraph, explaining that \footnote is fragile and cannot be used in those contexts without \protect.  Manually adding \protect before \footnote in the automatically-generated tex file appears to produce correct results.

I don't know if the best fix is to always \protect \footnotes in LaTeX export, or if more contextual smarts are required, but this seems like an issue worth addressing.  

Cheers!
