Description Patrick Silva 2019-10-19 12:04:12 UTC

Application: systemsettings5 (5.17.80)

Qt Version: 5.13.1
Frameworks Version: 5.64.0
Operating System: Linux 5.0.0-29-generic x86_64
Distribution: KDE neon Unstable Edition

-- Information about the crash:
This crash only affects the icon view.
- What I was doing when the application crashed:
open system settings
open "colors" kcm
click on "All settings" in the upper left corner
try to open "Plasma style" kcm
system settings crashes

The crash can be reproduced every time.

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

Hopefully fixed by aea58fcca35984fff73e1c77dc2edb346da4e69b in kcmutils.

Are you able to find out if you have that?

this problem is happenng on Arch Linux after upgrade to frameworks 5.64.

open system settings in icon view mode
open any QML KCM
go back to "All settings"
open any QML KCM again
crash

I want to reproduce it, but what are the steps to open the "system settings" in "icon view mode" and where do I find "All settings" "in the upper left corner"?

Can you please guide me, maybe with screenshots as well?
Then I can probably tell you if #414099 is likely related or not.

Comment 9 Patrick Silva 2019-11-13 18:38:51 UTC

you can set the icon view clicking on hamburger button, "Configure...".

Alright, in that case I cannot reproduce this bug on:

Operating System: Manjaro Linux 
KDE Plasma Version: 5.17.3
KDE Frameworks Version: 5.65.0
Qt Version: 5.13.2
