Application: systemsettings5 (5.17.5) Qt Version: 5.13.2 Frameworks Version: 5.68.0 Operating System: Linux 5.6.8-200.fc31.x86_64 x86_64 Distribution: "Fedora release 31 (Thirty One)" -- Information about the crash: - What I was doing when the application crashed: I started systemsettings5 from the command line to view any error messages. Using the "System Settings" GUI, navigate to Appearance -> Application Style -> Window Decorations. Clicked on the Plastik icon to edit the settings, and crash occurs. - Unusual behavior I noticed: I wanted to edit the Plastik settings as the Konsole window had no border width which was annoying me. Running systemsettings5 from the command line showed the following errors reported including a problem concerning border width. <prompt>$ systemsettings5 QQmlEngine::setContextForObject(): Object already has a QQmlContext Couldn't load plugin: "The shared library was not found."
