Bug ID: 431791
Summary: System settings allow selecting incompatible themes
from other DEs which results in crashes
Product: systemsettings
Version: 5.20.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: mapm...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.20.5)
Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.9.16-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 33 (Thirty Three)"
-- Information about the crash:
- What I was doing when the application crashed:
I click on window decorations or Plasma Style.
- Custom settings of the application:
I had ddark selected as an Application Theme. The issue reproduces 100% when I
am with it and never with my other themes. This theme probably comes from my
deepin DE installation. In my opinion it should not be displayed at all in the
menu.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
