Hello Nick, hi everybody,

Because I just have seen the solution to this problem, I inform you that
this "bug" was  made by \usepacakge{minted} in my setup.  I have deleted
all references to "minted" in my ~/.emacs.d/init.el and I have succeeded
to sent to me an email with a formula in a png image. 

Like the following one: 

$$ A \to B $$

I hope it will help also somebody else, maybe. 

Bye bye,

Jo.
