Hello,

I have the following customisation for LaTeX export in org:

  (add-to-list 'org-latex-packages-alist '("version=3", "mhchem"))

I updated org yesterday (and again today) and now I cannot export to
LaTeX without error.  The above line results in the following LaTeX
preamble line:

  \usepackage[version=3]{(, mhchem)}

which should actually be 

  \usepackage[version=3]{mhchem}

I will try to track this down to a particular commit later.

Thanks in advance,
eric
