[FreeNX-kNX] nxagent failure on FC5

After running successfully with FreeNX 0.4.x on FC3 for some time I am not
trying to get things going with FC5 but without much success. I keep getting:
1004 Error: NX Agent exited with exit status 1.
Here's what I've done. Can anybody tell me the (probably obvious) step I've
missed?
yum update
yum install freens
yum install kdebase
mv /usr/X11R6 /usr/X11R6_old
cp /etc/nxserver/node.conf.sample /etc/nxserver/node.conf
This gives me these versions:
freenx-0.5.0-2.fc5
nx-2.0.0-3.fc5
In node.conf I uncommented and set the following:
NX_LOG_LEVEL=7
SESSION_LOG_CLEAN=0
ENABLE_2_0_0_BACKEND="1"
These should be enough to give me useful log output and to get a connection
going. I can sort out printing and so on later.
The binary nxclient is not installed in the server. I assume the nxclient
script provides the functionality needed by the server as it does on 0.4.x
Using client nxclient-1.5.0-141 on gentoo amd64 (which works with the 0.4.x
server on fc3) I create a new connection for this server, change the key to
match the server's client.id_dsa.key and set it to enable SSL for all
traffic. Speed is 'Modem', desktop is 'KDE' and smb, cups and multimedia are
all off.
Starting a connection with these settings authentication completes, but
session startup fails. Logs are below.
The client shows:
