This is with Context 2013.05.28 00:36 MKIV (TL2013 on Debian).
the beta works ok .. are there any messages with respect to missing
fonts or map files?
FYI, with recent betas (2014.05.17 from a context standalone or
2014.05.21 from Debian TL2014), I still find the problem with the
internal mptopdf converter dropping glyphs.  I work around it in the
Makefile (convert using mptopdf externally).  However, in case it is
worth tracking down, here is the original report with the minimal
example.
you see the message:

LuaTeX warning (file cmr10): Font cmr10 at 3000 not found

so you need to load a map file that matches the used fonts:

\loadmapfile[mkiv-base]
...
==================
The internal mptopdf converter in MkIV omits some glyphs in the labels.
Here's a minimal example (test.tex):
\starttext
\externalfigure[testfig.1][frame=on]
\blank
\externalfigure[testfig-1.pdf][frame=on]
\stoptext
And testfig.1 is produced by testfig.mp
beginfig(1)
label(btex $\Omega$ etex, (0,0));
currentpicture := currentpicture scaled 5;
endfig;
end
Here's testfig.1 to save a step in debugging:
%!PS
%%BoundingBox: -18 -18 18 18
%%HiResBoundingBox: -17.98805 -17.0195 17.98798 17.0195

%%EOF
Then do:
mptopdf testfig.1
   context test.tex
   xpdf test.pdf
The first framed box, using the internal mps->pdf conversion, is empty.
The second framed go, using the pdf file produced by mptopdf, correctly
contains \Omega.
