Sorry, that's a bad example. The music player should emit a signal when it 
changes song. Polling is not a good idea.

Also, if you want to call a service only if it is already running, you can set 
the do-not-start flag on the message.

Ok, that's a valid use-case now :-)

So I agree we should have a connect-to-bus-but-don't-launch-if-not-running 
mode.

I suggest it be fixed there in the first place. The new feature to D-Bus is 
not anything critical, so gconf should not be depending on it to work 
properly.
