Just some more information ... Looking into the filename.1 makes me
very suspicious:

What exactly does "begindraw" do in EPS file? Adding ec-lmr12 and
lmmi12 into pdftex.map got rid of the error, but didn't generate any
valid output (it created an empty pdf). What mptopdf run on filename.1
does is basically
    pdftex -fmt=mptopdf -progname=context \\relax mathmp.1
(maybe I'm wrong; but it behaved exactly like that), but I didn't
manage to get any sensible output out of that.
