Application: khelpcenter (5.7.6.21041)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.12.3-arch1-1 x86_64
Windowing System: Wayland

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

Selected Tools > Add Signature
Drew a rectangle to hold a Signature
Got a message reading that there is no Signature and that I can consult Okular help on how to add a signature
Clicked on the hyperlink
Okular help opens and crashes immediately

The crash can be reproduced every time.

-- Backtrace:
Application: Centre d'aide (khelpcenter), signal: Segmentation fault
