I have similar problems with
x11vnc 0.9.13-1
libvncserver0 0.9.9+dfsg-1 0
when starting with -no6 -noipv6 -rfbport 5902, I saw the output of:
25/01/2013 12:15:51 Listening for VNC connections on TCP port 5902
25/01/2013 12:15:51 Listening for VNC connections on TCP6 port 5900
and netstat -atpn showed x11vnc listening on :::5900
However, after downgrading libvncserver0 to 0.9.7-2+b1, this doesn't happen
anymore.
