Do an 'rpm -q packagename' for some or all of the packages in question 
to see if you have duplicates installed (or rpm thinks you do).  I had 
this happen on one machine where yum crashed during the 5.3 upgrade and 
there really were many duplicates left in the rpm database and 
yum-complete-transaction did the right thing in removing them, even 
though it was bit scary to do remotely.
