krdc is unable to connect to VNC servers after updating libvncserver from 0.9.7 to 0.9.8 or 0.9.8.1.

When I inspect the traffic using wireshark, it looks like it is unable to authenticate.

This doesn't work:
kdenetwork-krdc 4.7.90
libvncserver 0.9.8

I also tried 0.9.8.1 and it also doesn't work.

This does:
kdenetwork-krdc 4.7.90
libvncserver 0.9.7

When it works (with 0.9.7) the wireshark shows following data:
(S = Server, C = Client):
S->C: Server protocol version: 003.889
C->S: Client protocol version: 003.008
S->C: Number of security types: 3
      Security type: Unknown (30)
      Security type: VNC (2)
      Security type: Unknown (35)
C->S: Security type selected: VNC (2)
S->C: Authentication challenge: 3a9c(...)
C->S: Authentication response: 8aa5(...)
S->C: .... .... .... .... .... .... .... ...0 = Authentication result: OK

And the rest of the VNC session continues.

With 0.9.8.1 it shows:

S->C: Server protocol version: 003.889
C->S: Client protocol version: 003.008
S->C: Number of security types: 3
      Security type: Unknown (30)
      Security type: VNC (2)
      Security type: Unknown (35)
C->S: Security type selected: Unknown (30)
S->C: Security type selected: Invalid (0)

And the client closes the connection. Also, the KRDC could show something, an error message, or at least a message saying that the connection was closed. Instead it just sits there doing nothing, so there is no way to tell whether it's just waiting to connect, or that something failed...
