Description Henning 2020-06-14 12:09:28 UTC 
Application: systemsettings5 (5.19.0)

Qt Version: 5.15.0
Frameworks Version: 5.70.0
Operating System: Linux 5.6.14-1-default x86_64
Windowing system: Wayland
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:

Fresh Tumbleweed installtion, changed the button style to dark (in X11 even). Now clicking on any setting Icon in System Settings will crash it. BT is from Wayland but it's the same on X11.

- Unusual behavior I noticed:

Context menus are broken (blank no text), as well as File/Edit/View on Konsole

- Custom settings of the application:

Just the mentioned icon theme.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault

Comment 7 Henning 2020-10-27 20:03:11 UTC 
Sorry I don't remember from which status I was switching to. I hope I find the time to check if it happens with the current state in Tumbleweed (5.20 etc) and if I can provoke it again. I can't promise it though.

Comment 3 shows you indeed switched to bb10dark. Please report this issue directly to bb10dark authors.

>widgetStyle=bb10dark

You are using bb10dark, it is broken, and it is crashing. Please report a bug there.

The openSUSE folks. They're the ones shipping it by default, at least.

Arch is a DIY distro which means you must have installed that style yourself, or gotten it pulled in automatically as a dependency of something you did install. So find the relevant package for the bb10dark theme, examine its metadata, and contact the developers of the theme.

If none of that makes sense to you, you should probably ask for help in an Arch-specific forum or user support group.

This bug with using the chameleon style has been solved now: https://github.com/linuxdeepin/qt5integration/issues/49

The problem was  apparently not in the chameleon style, but in the associated dde-qt5integration. I've tested it with dde-qt5integration 5.5.17, and it does not crash any more. Following the comments in the bug report, it has been solved since dde-qt5integration 5.1.0.13.
