Sentry Crash Report:

Description K.-Michael Aye 2022-08-11 12:26:51 UTC 
Application: systemsettings (5.25.4)

Qt Version: 5.15.5
Frameworks Version: 5.96.0
Operating System: Linux 5.15.0-43-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.25
DrKonqi: 5.25.4 [KCrashBackend]

-- Information about the crash:
System was on lock with automatic sleep after 30 minutes.
Monitor (HP Z32) was showing data on other input port when THIS machine was woken up and the input source changed to THIS machine.
After monitor came back to like, I saw an empty Display settings window (presumably from the time the monitor was still sleeping), which then crashed within a second.

The reporter is unsure if this crash is reproducible.

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

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #4  0x00007f08a0eca446 in KScreen::Config::outputs() const () from /lib/x86_64-linux-gnu/libKF5Screen.so.7
> #5  0x00007f08a0f42835 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/plugins/kcms/kcm_kscreen.so
> #6  0x00007f08d2bbc546 in ?? () from /lib/x86_64-linux-gnu/libKF5KCMUtils.so.5
> #7  0x00007f08d2bbb89f in KCModuleProxy::save() () from /lib/x86_64-linux-gnu/libKF5KCMUtils.so.5

Could you please install debug symbols for kscreen the frameworks-kcmutils, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
