Description devhexorg 2024-04-15 12:08:32 UTC 
Application: systemsettings (5.27.11)
 (Compiled from sources)
Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.6.21-gentoo-dist x86_64
Windowing System: Wayland
Distribution: "Gentoo Linux"
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
Despite having internet connection the download window was having trouble loading any content. I tried closing it and opening it again, but when I opened it again the whole system settings application crashed. I was not able to reproduce the issue the second time and the download window instantly connected and showed me all the KDE downloadable content. On opening it again no crash happened.

The crash does not seem to be reproducible.

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

New crash information added by DrKonqi

systemsettings (5.27.11) using Qt 5.15.9

The most specific way to recreate the bug is by opening "System Preferences", "Appearance", going to "Application Style", choosing "Configure gnome application style", a button at the bottom right, and this opens a window, then "Get new application styles" and right there it crashes.
