Description BWallfacer 2022-03-28 11:53:54 UTC
Application: systemsettings (5.24.3)

Qt Version: 5.15.2
Frameworks Version: 5.92.0
Operating System: Linux 5.17.0-051700-generic x86_64
Windowing System: X11
Distribution: Ubuntu Jammy Jellyfish (development branch)
DrKonqi: 5.24.3 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I opened system settings and navigated to systemd under System Administration.
Clicked the user units tab and filtered by Automounts.

Result is 545 units, 437 active and 0 displayed.
When clicking the empty area (found it's right click) where units are listed, the application segfaults.

Possibly unrelated: disk latency is higher than usual as I was copying some large files and running a btrfs balance

The crash can be reproduced every time.

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

I'm afraid this KCM is no longer maintained or supported. I would encourage you to encourage the Kubuntu folks to either stop shipping it, or to take over maintenance of it themselves.
