dvipdfm problem with the matplotlib eps files

My lovely matplotlib EPS graphics are missing in my PDF
files if I use dvipdfm. It looks (?) like they are included
but then are blanked out afterwards. Any idea why? I have never had
trouble with other EPS files.

I tried cutting out all the page size stuff in the EPS file
(what is that about?) but it did not help.

Using dvips and ps2pdf gives a fine result.
The EPS files appear to be valid, but must be doing
something that upsets dvipdfm.

Thanks,
Alan Isaac
