Sorry, I left out a couple of things I meant to say...

Basically, when we run with uniqueMPgraphic instead of useMPgraphic, we
get a lot fewer mpgraphic files; but the tables we produce lack the
outer border. And we get the above errors.

Googling the errors leads us to dvipdfmx, e.g.
http://tug.org/texlive/devsrc/Build/source/texk/dvipdfmx/src/spc_pdfm.c
http://dvipdfmx.sourcearchive.com/documentation/1:20050831-5/pdfximage_8c-source.html

But I don't think dvipdfmx is the cause.
Can anyone explain the error messages or suggest a fix?
We would love to use uniqueMPgraphics for efficiency, but we can't if it
gives the wrong result...

Thanks,
Lars
