Commit fbd66cdc exposed this preexisting bug. Before sModel was always a PlasmaCore.SortFilterModel but now that we can hit the !showHiddenDevices.visible condition in main.qml:546/573 it can also just be a normal SourceModel or SinkModel that do not have a get() method like the SortFilterModel. So we have to access the data properly. BUG:427687 FIXED-IN:5.20.1
