Hi I want to sent the following message

* Matlab code
f=@(t,y)[-t*y^2];
[t,y]=ode45(f,[0 1],1);
t=[t(1),t(end)];
y=[y(1),y(end)];
disp('\begin{align*}')
fprintf('t = [%g  \\quad %g]  \\\\\n', t)
fprintf('y = [%g  \\qquad %g] \n', y)
disp('\end{align*}')


And I want to run org-mime-htmlize. When I do this the function
complains about the incorrect latex syntax. So I set
(setq org-html-with-latex nil),
either like this or with customize-option
I even check that it is indeed nil, run again
org-mime-htmlize.

But then I obtain the *same error* and now the variable is,
magically, set to dvipng!!!!


What the heck is going on?
