I've managed to get some more insight into original problem. It seems that after some system updates, desktop database gets updated, and that triggers a bunch of onSourcesChanged+onSourcesRemoved events, followed by a bunch onSourcesChanged+onSourceAdded events. Since I'm on rolling distro i get updates very frequently and this problem happens to me pretty frequently. After .desktop database is updated these events are fired on 'apps' dataengine: .... bunch of events for various .desktop files.... Sep 08 00:44:19 onSourcesChanged() onSourceDisconnected() org.kde.ksysguard.desktop onConnectedSourcesChanged() onSourceRemoved() org.kde.ksysguard.desktop .... bunch of events for various .desktop files.... Sep 08 00:47:01 onSourceAdded() org.kde.ksysguard.desktop .... bunch of events for various .desktop files.... Sep 08 00:47:43 onSourceRemoved() org.kde.ksysguard.desktop .... bunch of events for various .desktop files.... Sep 08 00:49:54 onSourceAdded() org.kde.ksysguard.desktop .... bunch of events for various .desktop files.... No onSourceConnected() event was fired for "org.kde.ksysguard.desktop" after it has been disconnected -> removed -> added -> removed -> added. It wasn't connected to datasource again after it was updated and re-added and thus apps.data["org.kde.ksysguard.desktop"] became undefined. I can look into fixing/changing apps dataengine and making it re-connect "lost" sources if that is desired. Is that supposed to happen automatically or is qml script supposed to re-connect "lost" sources during onSourceAdded event?
