I believe the dbus errors have been solved by amending .xinitrc to read
Code:
PATH=/usr/local/kde4/bin:$PATH
export PATH
#startkde4
exec dbus-launch --exit-with-session startkde4
The previous edit made to /usr/local/share/apps/khtml/css/html4.css does not appear to affect KDE3.5.10
I still have 2 systrays. And still some issues with kopete. But I'll start new threads for those specifically.
