Sentry Crash Report:

Description beniiorga 2021-06-24 13:46:05 UTC 
Application: systemsettings5 (5.22.2)

Qt Version: 5.15.3
Frameworks Version: 5.83.0
Operating System: Linux 5.8.0-59-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.2
Distribution: KDE neon User Edition 5.22

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

I was trying to edit the name of an online account I had just added and when I pressed ctrl+a to overwrite the old name it crashed. Probably has nothing to do with this as I was also doing updates in the background, but it's worth a try

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault

This is an upstream bug in Qt which was fixed with https://codereview.qt-project.org/c/qt/qtdeclarative/+/371842. It will be backported to the KDE patch collection soon; see https://invent.kde.org/qt/qt/qtquickcontrols2/-/merge_requests/3

Thanks so much to Nicolas Fella for discovering this and backporting it!
