WARNING: attempt to net_add_domain(netgraph) after domainfinalize()

I get this message on bootup, i have an adsl connection using the system 
ppp. It seems like it is the process of loading modules and establishing 
the connection that does this. Anyone know why this is happening, and if 
its harmless, perhaps it would be better to silence it?
