Created attachment 109249 [details] screen shot Bugs in Neon/dev/stable 20171205 build 1. in System Settings > Workspace Theme > Look and Feel there are no entries to select. It's just a blank screen. 2. In System Settings > Workspace Theme > Desktop Themes there no entries to select. Just a blank screen. These bugs are not in the dev/unstable release of the same date and they were not in earlier dev/stable releases but I don't know when they first appeared.
confirmed on my neon dev unstable. plymouth-kcm is also affected.
You are using the 'Sidebar View'. Is there same problem with the other 'View Styles' ? or if you start the single system settings module from the terminal. Any error messages ? Look and Feel: 'kcmshell5 kcm_lookandfeel'
Could be missing 'qml-module-org-kde-kcm'. More: - https://forum.kde.org/viewtopic.php?f=309&t=143221 - https://forum.kde.org/viewtopic.php?f=309&t=143293

Ack. $ kcmshell5 kcm_lookandfeel org.kde.kcoreaddons: Error loading plugin "kcm_lookandfeel" "The shared library was not found." Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") The environment variable QT_PLUGIN_PATH might be not correctly set "file:///usr/share/kpackage/kcms/kcm_lookandfeel/contents/ui/main.qml" "Error loading QML file.\n28: module \"org.kde.kcm\" is not installed\n" and the window that appears is empty. Running $ sudo apt-get install qml-module-org-kde-kcm fixes it. This should be marked as confirmed in KDE Neon, and the dependences of the package fixed.
this bug affects Arch Linux. There is no qml-module-org-kde-kcm or another package with similar name in its repositories.
And nothing that provides libkcmcontrolsplugin.so ? Then Arch Linux is missing what should be a core KDE package (it's present in upstream Neon, just the depdancy information is missing)...

plasma 5.12 has the same bug on Arch Linux.

Problem persists in plasma 5.12.4, Arch Linux.
On my Arch Linux (plasma 5.12.4) the problem occurs only when I set system settings to icon view mode. Tree and sidebar views are not affected.
in kde forum, a neon user reported the same bug in sidebar view https://forum.kde.org/viewtopic.php?f=309&t=152514&p=399033#p399033

> "Error loading QML file.\n28: module \"org.kde.kcm\" is not installed\n" If this is your issue, it's a packaging problem.
