Plasmoid now uses KRun::openService() to launch ksysguard instead of KRun::openUrl() and apps data source.
After plasmoid has been running for some time (several hours, maybe days), clicking it would produce error:
"file:///usr/share/plasma/plasmoids/org.kde.plasma.systemloadviewer/contents/ui/SystemLoadViewer.qml:389: TypeError: Cannot read property 'entryPath' of undefined"
instead of launching ksysguard.
Ksysguard now starts without delay after click, since url doesn't have to be looked up.
