Dear list,

Since about a week, exporting directly to Beamer ceased to work. See
the attached Minimal.org file :

 - This file exports perfectly to a LaTeX file (via C-c C-e l b).

 - The resulting Minimal.tex exports perfectly to Minimal.pdf.

 - Trying to export directly to PDF via C-c C-e l P fails ; content of
the *Messages* buffer :

-----------------
Saving file /home/charpent/Boulot/Cellule
Innovation/BayesDec/Minimal.tex...
Wrote /home/charpent/Boulot/Cellule Innovation/BayesDec/Minimal.tex
Processing LaTeX file Minimal.tex...
Wrong type argument: sequencep, 108
-----------------

 - Ditto when exporting to PDF via C-c C-e l p (= export to PDF withot
making frames at header level 2).

Retrying Beamer PDF export with debug-on-error set to t gives me the
following backtrace :

-----------------
Debugger entered--Lisp error: (wrong-type-argument sequencep 108)

-----------------

which isn't very helpful... Any hint would be welcome.

Sincerely yours,

PS : CC me would be appreciated : I'm not on the list, and read it via
the archive...
