Operating System: Linux 6.1.0-2-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux bookworm/sid
DrKonqi: 5.26.90 [KCrashBackend]

-- Information about the crash:
I've noticed since a recent update that opening Window Decorations immediately crashes the system settings. Because I'm running Debian Testing I assumed this information might be useful. 

Operating System: Debian GNU/Linux 
KDE Plasma Version: 5.26.90
KDE Frameworks Version: 5.102.0
Qt Version: 5.15.8
Kernel Version: 6.1.0-2-amd64 (64-bit)
Graphics Platform: X11
Processors: 4 × AMD A10-7700K Radeon R7, 10 Compute Cores 4C+6G
Memory: 7.7 GiB of RAM
Graphics Processor: AMD Radeon RX 460 Graphics

The crash can be reproduced every time.

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

Comment 2 Martin Kyral 2023-02-01 11:35:11 UTC

I am experiencing the same segfault on Fedora 37 and just now I noticed the likely cause: mixed packageset. You (and me too) are having installed plasma-systemseting 5.26.5 on top of 5.26.90 plasma.

Comment 3 Martin Kyral 2023-02-01 11:50:08 UTC

Fixing the packages fixed the segfault. Do make sure you have all of the packages in the same version.
