I'm seeing the same problem on plain Debian with xpdf and evince -- it's
one of several problems that were introduced as part of security fixes
in libpoppler46 0.26.5-2+deb8u2. ...+deb8u1 works OK, if you don't need
the security fixes.

There are a couple of Debian bugs about this already:
https://bugs.debian.org/886798
https://bugs.debian.org/890826

Thanks,
