system-config-cluster-1.0.24-1.0 is the version that the development 
repository carries.. The version seems to require the below.

You might try to remove the version that you have installed and 
temporarily activating the fedora-devel-repo and using yum to install 
system-config-cluster and matching versions below.
If s-c-cluster is available for FC4, (I thought that it was, have not 
checked) yum install the package from the FC4 version to install it.
I have not personally worked with the cluster manager to actually create 
a cluster file system. I was able to save the config file with a few 
bogus entries without the problem that you describe when saving the changes.

rpm -q --requires system-config-cluster
/sbin/chkconfig
/usr/bin/python2
config(system-config-cluster) = 1.0.24-1.0
gnome-python2
gnome-python2-canvas
pygtk2
pygtk2-libglade
python >= 2.3
rhpl >= 0.148.2
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1


-- 
Well fix that in the next (upgrade, update, patch release, service pack).
