Application: akregator (5.19.3 (21.12.3))

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-40-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04 LTS
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
What I was doing when the application crashed: 
Simply starting the app.  A "do you want to recover your session" message shows up, but before I can even click it, the app segfaults. 

I can't speak to causation tthough because both began at once.

Happy to help any way I can.

Note: I compiled akregator (not the whole platform) from source to get a debug package (see https://bugs.launchpad.net/ubuntu/+source/akregator/+bug/1980888) but the same issue is occuring in Ubuntu's deb package version 4:21.12.3-0ubuntu1.

The crash can be reproduced every time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
