This is normal if you're not running nm-applet or the KDE workspace
network management stuff.

I think this is fixed about a year ago (in NM 0.8.4 and later); it's
really the client libs asking whether this ActiveConnection is a VPN or
not, and the Vpn property is what indicates that.  Can you run the
following command when you see this, replacing the object path with the
one from the error?

dbus-send --system --print-reply
--dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager/ActiveConnection/XXXXX org.freedesktop.DBus.Properties.GetAll string:"org.freedesktop.NetworkManager.Connection.Active"

ie, replace the XXXXX with '9' here and tell me what you find.
