            Bug ID: 418738
           Summary: Okular crashes when open digital signed PDF (?)
           Product: okular
           Version: 1.8.3
          Platform: Compiled Sources
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: elxreno at gmail.com
  Target Milestone: ---

Application: okular (1.8.3)
 (Compiled from sources)
Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 5.5.8-200.fc31.x86_64 x86_64
Distribution: Fedora 31 (KDE Plasma)

-- Information about the crash:
Every month one service sends me a PDF (probably digital signed) and I can't
open it with Okular.
Also I can't share this PDF because it contains private data.

PDF created in StreamServe Communication Server 5.6.2 GA Build 840 (64 bit)

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
