I don't have the impression that the error lies in `ob-latex' as the other
`ob-LANG' files don't either make any special check -- while all graphics-only
languages do, as well, have the default of "results" for ":exports".

I have the impression the problem is to search in `ob-core'
(`org-babel-execute-src-block') or `ob-exp'... But that's not yet clear to me
where that could be.

FYI, I have collected extra information about the problem: it is the file-wide
property which is not taken into account (only in the case of the LaTeX code
blocks, though).

If we put the header argument ":exports both" on the code block itself, I get
the expected result...

--8<---------------cut here---------------start------------->8---
#+TITLE:     ECM skeleton.org
