kbuildsycoca crashes

I am running Fedora Core 3 on a SOTEC PC cobbled together with parts from 2 PCs we were about to scrap. After swapping network cards around etc, I finally got things going and here I am.

I installed KDE as I have done on many many occasions with other PCs simply using the usual install process provided by the Fedora Core 3 installation disks. I can get on with my work as usual but I often receive a message from the KDE Crash Handler:
The application KBuildSycoca(kbyuildsycoca) crashed and caused the signal 11 (SIGSEGV)

Recently I got:
The application KDE Menu Editor (kmenuedit) crashed and caused the signal 11 (SIGSEGV)

I tried rebuilding the ksycoca database by running
$ kbuildsycoca
I got the following messages:
kbuildsycoca running...
Reusing existing ksycoca
KCrash: Application 'kbuildsycoca' crashing...

When I run as root:

# kbuildsycoca

I get

Warning: kbuildsycoca is unable to register with DCOP.
kbuildsycoca running...
kbuildsycoca running...
KCrash: Application 'kbuildsycoca' crashing...
kdeinit: Shutting down running client.
Mutex destroy failure: Device or resource busy
---------------------------------
It looks like dcopserver is already running. If you are sure
that it is not already running, remove /root/.DCOPserver_localhost.localdomain__0
and start dcopserver again.
---------------------------------

KDE Daemon (kded) already running.
KCrash: Application 'kbuildsycoca' crashing...

I have trawled through the internet and searched these forums and read lots of documentation about KDE (which frankly I didn't want to know. I just want to use KDE to run other things). So far, I have found this problem all over the place with many users having difficulty, but I have not found a solution yet.

As far as I can tell the KDEDIR environment variable is correctly set to /usr. Here is my /etc/profile.d/kde.csh:

# Make sure KDEDIR is set
if ( $?KDEDIR ) then
exit
endif
setenv KDEDIR /usr

I've forgotten the command that displays kde home but when I did run it it gave me /usr.

Can anyone suggest which configuration files I need to edit to make sure kbuildsycoca can build the ksycoca and stop crashing?
