            Bug ID: 470446
           Summary: Crash While Editing Forms
    Classification: Applications
           Product: okular
           Version: 23.04.1
          Platform: openSUSE
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: ismailsahillioglu at gmail.com
  Target Milestone: ---

Application: okular (23.04.1)

Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 6.3.2-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
I was filling and editing forms in a document. When I enabled the forms for the
next time the blinking cursor was appearing in each field, I think each field
was having the focus at the same time. Then it crashed after a while.

The reporter is unsure if this crash is reproducible.

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