            Bug ID: 426020
           Summary: Okular crashes when attempting to open .cbr files
           Product: okular
           Version: 1.11.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: ben.schroeder at protonmail.com
  Target Milestone: ---

Application: okular (1.11.0)

Qt Version: 5.15.0
Frameworks Version: 5.73.0
Operating System: Linux 5.8.2-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed: Trying to open a file in the
.cbr (comic book) format.

- Unusual behavior I noticed: The application opens for a second but doesn't
display any content, then crashes.

The crash can be reproduced every time.

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