Created attachment 100860
  --> https://bugs.freedesktop.org/attachment.cgi?id=100860&action=edit
the pdf that pdftocairo can't render properly

In the attached pdf file, there is an area filled with grid-like pattern.
and pdftocairo -svg renders the area with many horizontal gaps. pdftoppm
doesn't have this problem.

I build poppler from latest master 1b705331019b155f2138d4b9f5a5bd03ec59193d on
ubuntu 14.04. configuration:
