            Bug ID: 309528
          Severity: crash
           Version: 0.15.2
          Priority: NOR
          Assignee: okular-devel at kde.org
           Summary: Okular crashes upon opening PS file
    Classification: Unclassified
                OS: Linux
          Reporter: pancho.mz at riseup.net
          Hardware: Chakra
            Status: UNCONFIRMED
         Component: general
           Product: okular

Application: okular (0.15.2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.6-1-CHAKRA x86_64
Distribution: "Chakra"

-- Information about the crash:
- What I was doing when the application crashed:

I opened a simple PS file (created with Scribus) using Okular.

This immediately killed Okular:
  GPL Ghostscript 9.05: Error: Font Renderer Plugin ( FreeType ) return code =
-1
  GPL Ghostscript 9.05: Error: Font Renderer Plugin ( FreeType ) return code =
-1
  invalidaccess -7
  KCrash: Application 'okular' crashing...
  KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
  sock_file=/home/pancho/.kde4/socket-Luka/kdeinit4__0
on Chakra with:
  okular: 0:15.2
  libspectre 0.2.6.1
  ghostscript: 9.05
  freetype2: 2.4.7

It is nearly 1:1 reproducible with the following output:
  GPL Ghostscript 9.06: Error: Font Renderer Plugin ( FreeType ) return code =
-1
  GPL Ghostscript 9.06: Error: Font Renderer Plugin ( FreeType ) return code =
-1
  invalidaccess -7
  okular: Fatal IO error: client killed
  KCrash: Application 'okular' crashing...
  KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
  sock_file=/home/pancho/.kde/socket-anna/kdeinit4__0
on Kubuntu 11.10 with:
  okular: 0.15.2
  libspectre: 0.2.7
  ghostscript: 9.06
  libfreetype6: 2.4.10

Whereas the PS file displays nice with: <gs Dokument-1.ps>

This bug is probably related to
https://bugs.freedesktop.org/show_bug.cgi?id=20138 in libspectre, especially as
Evince also fails displaying the file.

However libspectre's failure shouldn't make Okular crash, but should at least
show an error.


Btw, the Freetype patch:
https://savannah.nongnu.org/bugs/?func=detailitem&item_id=35833 /
http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=9a55cb7a
and the followup:
https://savannah.nongnu.org/bugs/?func=detailitem&item_id=35847
http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=b43e0f44
should have fixed the Font Renderer Plugin issue in 2.4.10, but I'm not sure it
has.
Does someone know whether libspectre comes bundled with an old version of
freetype?
Then I'd know whether to file this against freetype or libspectre.

The crash can be reproduced every time.
