But mptopdf has no connection with any LaTeX package at all. It's a
pure ConTeXt script, which used to support LaTeX input as well until
ConTeXt has switched to ruby (and there should be no reason why it
would not support that now).

Exactly that was the problem: no LaTeX user has ever updated the
distribution (there was nothing comfortable to update after all until
TeXLive 2007 came out) and tried to use mptopdf to process metapost
code with LaTeX commands. I completely forgot (would never come to the
idea to do that) to test that during transition to ruby (I only wrote
countless mails to Hans complaining that the new version still didn't
work). So I'm the guilty one ;)
On the other hand there is rarely a need to use LaTeX in such labels
(one can do the same on ConTeXt), but it's a matter of a habit. And
since that worked already, it should be fixed to work again.
I remember that Hans claimed that texmfstart (or texexec) could be
convinced to process LaTeX documents (and there is some mention of
latex command in core indeed), but I never managed to make it work.

pdfs in attachments tend to be long anyway. And LaTeX mailing lists
will be unable to answer that specific problem which was introduced in
ConTeXt.

He posted a minimal example:
%%%%%%%%%%%%%
verbatimtex
%&latex
\documentclass{article}
\begin{document}
etex
beginfig(0);
externalfigure "pic.png" scaled 15mm shifted origin;
label.bot(btex $x$ etex, origin);
endfig;
end;
%%%%%%%
One should save it as something.mp and compile it with
mptopdf [--someswitch] something.mp
