Created attachment 98133
easyjet boarding pass not rendered correctly

Hello, the attached PDF (easyjet boarding pass) is not correctly rendered under poppler (evince).
I am using Ubuntu 14.04 amd64, so evince 3.10.3 and poppler 0.24.5.

Evince prints a lot of messages like:
Syntax Warning: font matrix not invertible<0a>

while ghostscript renders the PDF correctly, but prints lots of:
   **** Warning: Invalid 0.0 font scale given for Tf ****
   **** Warning: /BBox has zero width or height, which is not allowed.

so I suspect the PDF is defective, but poppler should be made more "fault tolerant" as ghostscript does.
Otherwise, no boarding pass print anymore :-(

I can fix the PDF with
gs -q -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pdfwrite -sOutputFile=out.pdf in.pdf

Looks good in okular so it must be a cairo backend bug.

Yeah also for me in okular is ok. And no log messages on stdout at all.
