Using 4.9.3. Trying to add it to my panel. Here is what xsession-errors says

Code: Select all

plasma-desktop(843)/plasma TaskItemLayout::updatePreferredSize: Empty layout!!!!!!!!!!!!!!!!!!
plasma-desktop(843)/libplasma Plasma::isPluginVersionCompatible: unversioned plugin detected, may result in instability
plasma-desktop(843)/libplasma Plasma::PluginLoader::loadApplet: Couldn't load applet " "showdesktop" "! reason given:  "Could not find plugin 'Show Desktop' for application 'plasma-desktop'"
plasma-desktop(843)/libplasma Plasma::ContainmentPrivate::addApplet: Applet "showdesktop" could not be loaded.
plasma-desktop(843)/libplasma Plasma::AppletPrivate::init: Check your constructor!  You probably want to be passing in a Service::Ptr  or a QVariantList with a valid storageid as arg[0].

assume you just up'ed to 4.9.3, if so did the widget work earlier?

try:
1) running: kbuildsycoca4 --noincremental
2) assuming the Arch package is kde-meta-kdeplasma-addons, you might reinstall it
