           Summary: non-embedded PDF fonts cause segfault
           Product: poppler
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: general
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: stharward at gmail.com


When viewing the attached PDF in XPDF, libfontconfig segfaults trying to fill
in the non-embedded fonts.  I have filed a bug upstream with fontconfig
(because it shouldn't segfault at all), but Poppler is probably calling the
library improperly in the first place.

Here's the stack trace:
