[O] Wrong type argument: processp, nil

[David Arroyo Menéndez]

I've been having troubles using org-html-export-to-html in some files,
I can read in the mini-buffer Wrong type argument: processp, nil.

The problem was that in #+BEGIN_SRC, I was using shell instead of bash. I
think that the error showed is not intuitive, it could tell the number
of line or about #+BEGIN_SRC.

Thanks.
