Description Karol Bryd 2020-02-14 12:09:20 UTC
Application: systemsettings5 (5.18.0)

Qt Version: 5.14.1
Frameworks Version: 5.66.0
Operating System: Linux 5.5.2-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

I was trying to change the Plasma Style and theme - double clicking on the icon in panel causes KDE crashes handler to open.
Click on any of the appearance settings causes a crash, other system settings option open as expected.

- Custom settings of the application:

Nothing is really custom, pretty standard openSUSE desktop.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

>qbb10brightstyle

What is this?

Please can you try and identify where this is from for me.

It'll be some installed qstyle
Comment 2 Karol Bryd 2020-02-14 12:50:10 UTC
Yes, I installed some new themes recently from internet (via the KDE 'downloader'). It was OK until today, this morning I was playing with other themes and all windows lost correct decorations and instead there was just a black border.

To restore I have removed some of KDE settings related to themes (from ~/.config) and all is OK now. Not sure what exactly has happened but clearly you can break your KDE Desktop via System Settings by just changing and adding themes from internet.

I have the old broken config backed up in case you are interested investigating it further. Otherwise please close the ticket.
Comment 3 Kai Uwe Broulik 2020-02-14 13:17:23 UTC
I'm afraid the styles in qtstyleplugins seem quite outdated and buggy. The bb10 styles just crash all over the place because they never expect `widget` to be null, even though that being the default argument in `drawPrimitive`. I would consider BB10 style (as well as the entire platform - RIP) a lost cause.

The other styles in there, such as CDE, cleanlooks, gtk2, seem to mostly work but also have odd layouting issues at times.
