Could not start GNOME Web Browser
Startup failed because of the following error:
Unable to determin the address of the message bus (try 'man dbus-launch' and 'man dbus-daemon' for help'
My USE flags whilst emerging gnome did contain dbus and hald as specified in the gentoo gnome howto.
I can run epiphany using the command dbus-launch epiphany.
The dbus and hld services are also running at startup.
