Aha! You may be off the hook. It fails in the same way, at 400%. With
a ps file generated either way, it starts to render the image at that
magnification, then crashes.

If you have gv installed on your RHEL4 box, you can use that instead of
evince.

does not yield an error message. The problem seems peculiar to the way
gui apps are running gs, and to the mpl way of generating the
postscript, since it does not occur with cairo-generated postscript.
