Comment 2 Kai Uwe Broulik 2016-11-13 20:11:58 UTC 
Thanks for your bug report. Until we figure it out it should help if you disable the "Windowed Widgets" or "Standalone Widgets" plugin in KRunner settings.
Comment 3 Kai Uwe Broulik 2016-11-13 20:14:31 UTC 
Marco, all the WindowedWidgetsRunner does is iterating over Plasma::PluginLoader::self()->listAppletMetaData(QString()) - I could surely have it check for KPluginMetaData isValid but why does that list contain invalid applets in the first place?
