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
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.
