What command do you run to optimize the PDF?
user@ubuntu804server:~/manypdfs/fail2$ ~/pdfsizeopt/pdfsizeopt.py
--use-pngout=false Myriad\ Pro\ ReadMe.pdf

What does pdfsizeopt display when running the command above?

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

It works with --use-multivalent=false, though

The file you have attached is an encrypted PDF. pdfsizeopt (and Multivalent) 
don't support reading encrypted PDFs. I'll add a more helpful error message to 
indicate this.
