New crash information added by DrKonqi

systemsettings5 (5.23.4) using Qt 5.15.3

This crash on application startup began after the KDE neon User Edition upgrade from Plasma 5.23.3 to 5.23.4. Kinfocenter also crashes in the same manner.

-- Backtrace (Reduced):

Comment 5 thomas.werner 2021-12-06 16:34:45 UTC
Same here, but also, System Info Center shows the same crash behaviour. 
Also, in the automated DrKonqi report, I can not add any additional information (“What I did when …”).
Comment 6 S. Christian Collins 2021-12-06 16:38:42 UTC
I just confirmed this crash in a VirtualBox KDE neon install, so I'd be surprised if there was anybody on KDE neon not experiencing the crash after today's upgrade.

Comment 22 Clay Weber 2021-12-06 19:33:57 UTC
    It seems installing qml-module-org-kde-sonnet fixes this, among other issues.

    I noticed this trying to see why Neochat would not open after updating today, and saw an error:

    module "org.kde.sonnet" is not installed

    So I installed the package qml-module-org-kde-sonnet , which seems to have fixed everything
Comment 23 Nicolas Fella 2021-12-06 19:39:55 UTC
yes, that fixes it for me too
Comment 24 Rik Mills 2021-12-06 19:45:08 UTC
Should be fixed with: https://invent.kde.org/neon/kde/qqc2-desktop-style/-/commit/f1d90187b69f4729bf606d900e0ad3c9da96e421

Once the updated qqc2-desktop-style package are available in User edition.
