I've tried that approach also, it gives me the exact same problems.
MetaPost doesn't like some aspects of the *.mp file.  I'm not sure whether
there are some Dia components I could avoid that would dodge these problems,
but I really need those components that I've used (UML class with text,
connecting lines with arrows.)

I'll probably just end up exporting a *.eps file, or trying the approach
described by moritz.

If you ever get the chance to do some more papers, the little idiom I listed
below pulls all the metapost content throughout your document into a single
*.mp file.  You then run mp on that one file, creating a bunch of .1, .2,
.3, etc. files.  This file is then automatically included in the latex
document.

Of course, in the preamble, you need something like this...

\usepackage{emp}
\DeclareGraphicsRule{*}{mps}{*}{}

\ifx\pdftexversion\undefined
\usepackage[dvips]{graphicx}
\DeclareGraphicsExtensions{.eps}\else
\usepackage[pdftex]{graphicx}
\DeclareGraphicsExtensions{.pdf,.png,.mps,.mp}
\usepackage{epstopdf}
\fi

The epstopdf package lets you do seamless integration of *.eps files in a
pdflatex document.  If it encounters a *.eps file for which no *.pdf exists,
it creates one.

\begin{figure}
\begin{emp}
\input diagram.mp;
\end{emp}
