Exactly. That's why it's not possible.

Not all services implement introspection. Of those that do, some don't 
implement it correctly. Yet that's a valid situation. And some services 
don't reply at all to D-Bus (think of kioslaves), so you'll have 25-second 
timeouts in your script.

Unless you're reacting to user input (qdbus, qdbusviewer, a path completer 
in a shell or an editor, etc.), introspecting the D-Bus hierarchy is never 
right.

If you need to find a given service, either put it in the service name, or 
emit a signal and wait for all your clients to reply.
