`kcmshell5 kcm_kwin_virtualdesktops` works as advertised. /usr/share/kpackage/kcms/kcm_kwin_virtualdesktops/contents/ui/main.qml seems to be at fault. Motivation for accessing kcm_kwin_virtualdesktops: Desktop Cube Animation stopped working. Konsole kcmshell5 reports qml/org/kde/kirigami.2/FormLayout.qml:112:21: Unable to assign [undefined] to double Constructing a KPluginInfo object from old style JSON. Please use kcoreaddons_desktop_to_json() for "/usr/lib64/qt5/plugins/kwin/effects/configs/kcm_kwin4_genericscripted.so" instead of kservice_desktop_to_json() in your CMake code.
Using kcmshell5 kcm_kwin_virtualdesktops, Cube Animation started working when I changed the Rotation Duration to Default. Still crashes from the System Settings module. No longer an issue for me, since I can right-click the Task Manager widget to Configure Virtual Desktops in addition to kcmshell5. Would Qt 5.13.2 have something to do with it?
I copied the following from the tty used to launch kde. /usr/share/kpackage/kcms/kcm_desktoptheme/contents/ui/main.qml header: RowLayout { <—cannot anchor an item that isn't a parent or sibling. Trying to show an empty dialog. FormLayout.qml:112:21 unable to assign [undefined] to a double QQmlEngine: setContextForObject() – object already has a context `kcmshell5 kcm_kwin_virtualdesktops` works as advertised. Crash occurs every time I click Virtual Desktops in System Settings. Hope this helps find and swat this bug.
I figured out how to launch systemsettings5 in konsole so I could capture the crash output. Hope this helps find and swat this bug.
