            Bug ID: 466937
           Summary: Reproducible crash on PDFs from particular source
    Classification: Applications
           Product: okular
           Version: 22.12.3
          Platform: Kubuntu
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org
          Reporter: mariusz.woloszyn at gmail.com
  Target Milestone: ---

SUMMARY
Each time I try to open any of PDF files with invoice from particular issuer
the Ocular process crashes. It's 100% reproducible and happens on multiple
files from the same source. I didn't observe any adverse behavior with pdf
files from other sources.

STEPS TO REPRODUCE
1. Try to open the problematic pdf either by clicking on it, dragging into
Ocular o via File Open menu.
2. Since the PDF files causing the crash contain somewhat sensitive information
I can share them privately with developer when contacted.
