I have exactly similar problems with fboxes used for framing the tags (see
function `org-latex-format-headline-default-function'): I use the following
code for having nicer boxes around the tags:

  (format "\\hfill{}\\fbox{\\textsc{%s}}"

When such a code (\fbox) is put between the [], everything breaks... LaTeX
error...

AFAICS, there are 2 ways to solve this:

- not using the [] notation when the "short title" is exactly the same as the
  "long title"

- having an heuristic to clean the "long title" for converting it into a
  "short" one (like remove all LaTeX macros, keep text only -- not sure it's
  good, because the tags would be "glued" next to the title)

I guess the first point would make more sense. What do you think?

Best regards,
  Seb
