12.2 w/ konqueror installed. running it errors about dbus. adding dbus_enable="YES" to /etc/rc.conf fixed it.
dbus is basically assumed to be installed and running by everything gnome/kde.
So generally, if a package depends on dbus, it also wants it at runtime.

that in docs somewhere or do ppl just 'know'?

I get your point :) -- but we simply cannot add a warning to every modern Qt/Gtk application that uses dbus for ipc.
Maybe there should be pkg-message for devel/dbus to point out that it should be enabled.
Also there is  which arguably is also not quite up to date... :( But at least points to dbus.
