            Bug ID: 436408
           Summary: Okular crashes when opening docx file
           Product: okular
           Version: 21.04.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: sascha.gaspar at gmx.de
  Target Milestone: ---

Application: okular (21.04.0)

Qt Version: 5.15.2
Frameworks Version: 5.81.0
Operating System: Linux 5.11.16-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.21.4
Distribution: "openSUSE Tumbleweed"

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

I clicked on a docx file in an other application and it tried to open it with
Okular.

I wonder if Okular has a buggy file type checking or no check at all when it
tries to open a file. There are many bug reports related to this. E.g.:
426020
425725
417241
415261
408851
408818
406738
But this is only an assumption.

The crash can be reproduced every time.

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