YUM dependency issues

[The Joker]

Hi all,

I seem to have a problem with YUM.

I'm trying to update all packages using yum update, and the process 
fails with these messages:

--> Processing Dependency: koffice = 4:1.4.1-0.1.fc4.kde for package: 
koffice-devel
--> Processing Dependency: koffice >= 4:1.4.1 for package: koffice-l10n-it
--> Finished Dependency Resolution
Error: Missing Dependency: koffice = 4:1.4.1-0.1.fc4.kde is needed by 
package koffice-devel
Error: Missing Dependency: koffice >= 4:1.4.1 is needed by package 
koffice-l10n-it

As far as I can tell, this is telling me that I need koffice-1.4.1 or 
higher to install koffice-110n-it, and version 1.4.1-0.1.fc4.kde to 
install koffice-devel

rpm-q koffice shows this:
# rpm -q koffice
koffice-1.4.1-0.1.fc4.kde

Don't I already have the correct version installed?

Why is yum failing with dependency errors when the missing dependency is 
installed already?

Thanks for your help,

The Joker.
