Package: libcairo2
Version: 1.14.0-2.1+deb8u1
Severity: important
Dear Maintainer,
I was reading a PDF document when Evince got a SIGSEGV. I installed debug
packages and got the following backtrace using gdb:
Program received signal SIGSEGV, Segmentation fault.

I can provide the PDF document as well as the core file but due to their size
I can't attach them to this bug report.

Hi,
this bug was fixed in Poppler 0.43.0, as already Jason Crain marked
the bug (thanks!) -- hence closing.
Regarding backporting to Jessie (current stable): unfortunately the
patch breaks the ABI of libpoppler-glib, and thus it cannot be
backported to stable. Sorry.
Thanks for the report,
