What command do you run to optimize the PDF?
user@ubuntu804server:~/manypdfs/fail$ ~/pdfsizeopt/pdfsizeopt.py
--use-pngout=false --use-multivalent=true symbols-a4.pdf

What does pdfsizeopt display when running the command above?
The output is too long to paste here, but here are the beginning and ending
of the output...

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

There is an important limitation in the current implementation of pdfsizeopt: it
doesn't work reliably with Type1 fonts with >256 glyphs, and the attached PDF
contains such a font. Fixing this limitation would neeed a lot of work, 
including
adding a substantial new feature: CFF font unification.
