test PDF

Hello,
   pdftops appears to have trouble generating a ps file from this pdf.  I noticed this while using Okular, which could display the file correctly, but couldn't print. (It printed blank pages.)

I reported this to Okular bugs and got this reply:

True, poppler PSOutputDev seems to be creating invalid .ps for this file. This
is nothing we can fix since we rely on poppler PSOutputDev working correctly,
please go to https://bugs.freedesktop.org and report a bug saying that pdftops
creates and invalid .ps file for this pdf file.

You can reproduce the problem alone without okular doing:
  pdftops myfile.pdf
  gs myfile.ps

And see how gs complains the .ps file is malformed.


$ pdftops /tmp/win-form.pdf 
Error: Invalid Font Weight
