"Found 1 duplicate font objs"

[GoogleCodeExporter]

(The bug template asks me to choose a label, but there is no place to
choose one....)

What command do you run to optimize the PDF?
user@ubuntu804server:~/pdfsizeopt$ svnver/pdfsizeopt.py --use-pngout=false
--use-jbig2=false --use-multivalent=false Bishop-thesis.pdf

What does pdfsizeopt display when running the command above?

What's wrong with the optimized PDF?
There isn't one!

The attached file is the minimal example I could produce. I made it using
pdflatex with the MinionPro package.

Thank you for the detailed bug report. Ghostscript is generating two CFF fonts 
from
one original font for no apparent reason. I'm still debugging the issue.

Issue fixed in r91, after asking for clarification on the gs-devel mailing list.

Please verify that everything works with a larger document.

I can confirm that there is no longer the duplicate font error, so thanks for 
that.
However, now that there is an output file, I see some other problems with the 
larger
document. I will try to reduce these to a minimal testcase and open separate 
bugs for
them.

Cool, thanks. Having a minimal testcase for each bug saves quite a bit
of my time.
