org.kde.kcoreaddons: Failed to establish shared memory mapping, will fallback to private memory -- memory usage will increase

(kscreenlocker_greet:1930): GStreamer-WARNING **: External plugin loader failed. This most likely means that the plugin loader helper binary was not found or could not be run. You might need to set the GST_PLUGIN_SCANNER environment variable if your setup is unusual. This should normally not be required though.
