Running with --use-pngout=no is a temporary workaround.

A real fix would be ignoring the error.

FYI The problem cannot be reproduced on Linux.

Reproduced the problem on Wine 1.2 on the attacked d2b.pdf using

  $ wine pdfsizeopt_python.exe pdfsizeopt.py d2b.pdf

Fixed in r205 by adding the flag -force to the pngout command-line.
