Description Aleksa Savic 2022-05-15 07:58:30 UTC

Application: systemsettings (5.24.5)

Qt Version: 5.15.2
Frameworks Version: 5.93.0
Operating System: Linux 5.17.5-1-default x86_64
Windowing System: Wayland
Distribution: openSUSE Tumbleweed
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I opened the Display Configuration (in System Settings) and pressed on "Switch to Sidebar View". The app immediately crashes. Wayland session, openSUSE Tumbleweed in a VM, fresh install.

Tried it twice, it crashed. Tried the third time, it worked normally.

The reporter is unsure if this crash is reproducible.

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

How did you press the "Switch to sidebar view" button when you were viewing the Display & Monitor page? The button only appears when you're on the home screen.

Hi Nate, sorry if I wasn't clear. I'll upload a short video showing how I accessed it.

I tried it a few more times and got an another crash:

Comment 4 Nate Graham 2022-05-17 14:18:50 UTC

Got it, thanks. Can reproduce that way of showing the button. However it doesn't crash for me. Backtrace is the same as Bug 444599; marking as a duplicate and re-opening it.
