Hi Aaron. Thanks for the quick reply.

Based on what I see, I don't think this is the case. The service is
configured to automatically start up when a client tries to connect to
it. I've set this up via configuration in
"/usr/share/dbus-1/system-services" and it works fine, but only after
I restart Plasma, not before. In fact, once the service is up and
running, I can pkill it, and it starts right back up again if a data
engine is using it, which is kinda cool.

The only problem is that none of this works until I bounce Plasma.
Even if I start up the service manually (i.e. not relying D-Bus
auto-activation), I get an error when the data engine tries to
connect. Not the same error, but an error nonetheless.

I have tried sending SIGHUP to the dbus-daemon processes, but that
doesn't help. The only way I've been able to make it work is by
restarting Plasma.
