I want to do this as async and on-demand as possible (as database access can 
potentially be slow, doing i/o and stuff when data is requested) and I don't 
like this at startup. (This could potentially make Plasma and thus KDE startup 
slower -- I hate that.) Other dataengines behave similar, btw.

Why would you do that other than debugging?

The issue really is documentation for dataengine. Maybe we should a source 
"Documentation" to all dataengines? It would explain how to use it, i.e. a bit 
of text that explains how to go from an empty plasmaengineexplorer...
