Sorry for the noise : the bugs do exist, but my previous analysis was
false (one paren too much).
More data points :
* I installed also MathToWeb, and configured it in emacs
(via file-local-variables), with the same problematic result.
* The error message "LaTeX to MathML converter not configured"
appears exactly twice in org.el:
+ In org-format-latex
+ In org-create-math-formula
* In both cases, the call has the form :
=
(unless (org-format-latex-mathml-available-p)
(user-error "LaTeX to MathML converter not configured")))
=
* When evaluated from M-: (org-format-latex-mathml-available-p)
returns t (as it should...).
* I have been so far unable to trace the origin of the faulty
evaluations. I'll probably have to run an uncompiled org for this,
and I don't (yet) know how to do that.
Interim hypothesis : the relevant variables
(org-latex-to-mathml-jar-file and org-latex-to-mathml-convert-command)
may be inadvertently shadowed somewhere upstream in the call tree.
I'm afraid to be a bit out of my depth here...
Suggestions ?
