When trying to connect to a VNC server (vnc4server, version 4.1.1+xorg1.0.2-0ubuntu7). vncviewer logs the following: $vncviewer -log *:stdout:100 10.8.0.1:0 TigerVNC Viewer for X version 1.0.90 - built Aug 17 2010 17:52:57 Copyright (C) 2002-2005 RealVNC Ltd.

I have the same problem connecting to x11vnc with tigervnc-1.0.1_p2010052. You can add -SecurityTypes None as an argument to tigervnc as a workaround.
same here with tigervnc-1.0.1_p2010052-r2
googling, I found out that it's not a gentoo bug : see http://permalink.gmane.org/gmane.network.vnc.tigervnc.devel/720 if I understood it well, SecurityTypes is mandatory if server offers more than one type, and can be one of VncAuth,TLSNone,None.
Correct. Its a problem in the software itself, not something we can fix. So blame upstream
