Description İsmail 2023-05-30 11:50:37 UTC 
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

Hi Sune! Sorry for the late reply. This is because I didn't received notifications from the bugs.kde.org. Well I have attached the form in which I was getting crash. Please check it.
