>Description:
poppler has changed its API for getting PDF properties since 0.15.1
after the release of evince-2.32.0.

>     so this commit breaks the API again.

This change causes evince segfault when showing properties of
some PDF files.  To avoid this, evince must handle ``linearized''
property as boolean.

Generated with FreeBSD Port Tools 0.99

>How-To-Repeat:
Download a PDF file from
http://www.opm.gov/forms/pdf_fill/of0306.pdf
and open it with evince.
Choose Properties from File menu.

>Fix:
This fix is borrowed from
http://osdir.com/ml/general/2010-09/msg30460.html
Since poppler in FreeBSD is now 0.18.0, #ifdef's are not required.

This fix should be removed when evince is updated to 3.x.
