Poppler renders the attached file with an additional light gray area

Poppler renders the attached file with an additional light gray area in the
middle of the page. Both pdftocairo and pdftoppm have this issue.

Adobe reader and foxit reader don't, those area should be transparent. 

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