Communication error with launcher

[Max2009]

I am using Mandriva 2009.1 KDE 4.2
Whenever I try to run a program as root from the konsole I get this error.

# dolphin                                                 
<unknown program name>(13749)/: KUniqueApplication: Cannot find the D-Bus session server                                                                        

<unknown program name>(13748)/: KUniqueApplication: Pipe closed unexpectedly.

With KDE applications it looks like this:

# konqueror 
kdeinit4: preparing to launch /usr/lib/kde4/libexec/klauncher
klauncher(13763) kdemain: No DBUS session-bus found. Check if you have started the DBUS server.                                                                 
kdeinit4: Communication error with launcher. Exiting!

Needless to say, Konqueror and Dolphin are installed and working perfectly, under the user.

Why does this happen, and how do I fix it? I kinda need to be able to launch at least a text editor as root...

As user you can try: kdesu kwrite /select/file/location or as root just: kwrite /same/file

That is exactly what I tried.
BASH does not recognize the command kdesu ar user, and as root I get the above-mentioned error.

It would appear that the problem stems from this line:

No DBUS session-bus found. Check if you have started the DBUS server

I think the DBUS server has something to do with applications talking to each other...?
Anyway, it clearly works for User, but not for Root.
So, how do I start DBUS for Root? Preferably every login, automatically....
