Looking more closely I see that yum-utils was one of the packages updated, so actually it was yum-utils-1.1.17-2.fc10 that gave the traceback.

was yum being updated, too, when your transaction died?

also try this yum-complete-transaction

and tell me if it fixes it

or at least changes the problem.

Hi, it did solve the issue for me. 
I had 9 'outstanding' transactions to complete (lot of them being from 2007) and everything is finally cleaned up after executing your modified yum-complete-transaction with --cleanup-only parameter (otherwise it was trying to reinstall 1200 packages). 
I wonder if it's not some leftovers of past preupgrade interrupted processes that are now taken into account because there was some fc7 in the packages it was checking.
