krdc broke at 12.2

I have a problem with the new OpenSuSe release:
I run tigervnc-1.1.0 on Linux Mint(KDE) machine and previously I could easily connect to it via krdc from OpenSuSe. After the update to 12.2 krdc does not connect to vnc anymore, does not produce any errors - just shows blue background.
vncserver log shows:

 Connections: accepted:
 SConnection: Client needs protocol version 3.8
 SConnection: Client requests security type VeNCrypt(19)
 Connections: closed: (Clean disconnection)

Is there any way to make it working?
