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

What does pdfsizeopt display when running the command above?
info: This is pdfsizeopt.py r95.

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

Please update to r97 and try again. It should work.

By the way, the PDF generator is buggy, because it generates and RGB palette of 
size
25 (with an extra \n at the end). Nevertheless, r97 of pdfsizeopt.py now 
accepts this
buggy PDF, and ignores the extra \n.
