Why krdc (KDE 4.1.2) cannot connect to vnc server (RealVNC) ?

I setup a PC with Windows XP in a far far far away office. So I never want to go there...

I use RealVNC to establish a VNC server in that PC, and really want to use KRDC as my client to connect to RealVNC Server.

The problem is coming, I just cannot connect successfully via VNC protocol, the screen is blank (also black) and the state is connecting to "". I checked the network config, nothing wrong and I'm quite sure I can establish a TCP connection to the server on port 5900. Also make me confused, is that RDP protocol can work perfectly.

So I tried to start KRDC in my terminal. Now I can see something is wrong.

krdc(5700) HostPreferences::hostConfigured: Found:  "vnc://"
krdc(5700)/krdc (VNC backend) VncHostPreferences::readProtocolSpecificConfig: VncHostPreferences::readProtocolSpecificConfig
krdc(5700)/krdc (VNC backend) VncHostPreferences::VncHostPreferences: Show config dialog again
krdc(5700)/krdc (VNC backend) VncHostPreferences::showDialog: VncHostPreferences config dialog accepted
krdc(5700)/krdc (VNC backend) VncHostPreferences::saveProtocolSpecificConfig: VncHostPreferences::saveProtocolSpecificConfig
krdc(5700) MainWindow::statusChanged: -2
krdc(5700) MainWindow::statusChanged: -1
krdc(5700) MainWindow::statusChanged: 0
krdc(5700)/krdc (VNC backend) VncClientThread::run: --------------------- trying init ---------------------
krdc(5700)/krdc (VNC backend) VncClientThread::outputHandler: "VNC server supports protocol version 4.0 (viewer 3.8)"
krdc(5700)/krdc (VNC backend) VncClientThread::outputHandler: "Selected Security Scheme 50398725"
krdc(5700)/krdc (VNC backend) VncClientThread::outputHandler: "Unknown authentication scheme from VNC server: 50398725"
It seems the primary problem is about the last output "Unknown authentication scheme from VNC server: 50398725".
How to fix it? Help me!!!
