What MPL version are you using, and what non-standard rc settings are you
using? You must be using either usetex or ps.usedistiller, because
ghostscript is failing to produce a distilled file.
I just fixed a bug in the error report, please update from svn or change line
1333 in backend_ps.py to read:
if exit_status: raise RuntimeError('pdftops was not able to process your \
image.\nHere is the full report generated by pdftops: \n\n' + fh.read())
My experience has been that ghostscript fails like this when you are using the
usetex option, and your latex syntax is incorrect. Latex may not exit with an
error status, even though it encountered a problem, and the bad output is
propagated downstream to dvips and ghostscript. If you want a more specific
answer, please provide a specific example that produces your result.
