I've been having this exact same problem. Gnome is completly wrecked, and the reason the redhat updater isn't working right in KDE is because it trys to go online to check to see what's up, and I can't get online, so yea there you have it, no net=no redhat updater. But I can't figure out for the life of me how to get the net working again!!! HELP!!!!
some other comments- the error I get says that it is unable to contact the configuration server and lists some possible causes as being taht I need to enable TCP/IP networking for ORBit, or that I have stale NFS locks due to a systems crash it then lists a gnome site http://www.gnome.org/projects/gconf/
it also mentions the gconfd file.
when I try to install gnome from the FC3 boot disk I a unable to, in fact it seems like nothing gnome related is working at all (even gedit) any ideas???
