yes, but i don't think you want to do this in this case.

my guess would be that the dbus service does not exist yet. the code probably 
just needs to track the service coming and going. in fact, given your 
description, i assume that it probably also breaks if you stop the service and 
start it again while plasma-* is running.

see kdebase/workspace/plasma/desktop/runners/plasma-desktop for a small and 
simple example of how to watch for a dbus service being available.
