This has now been released upstream and it built for CentOS-6.4 ... will be released with a set up updates very soon (metadata building now).
Cheer Johnny - appreciate the quick turnaround ....
The semi-random named segfaults have been bugging me for a while now given I thought all updates had been applied... that'll teach me not to look at version numbers more carefully as opposed to just hitting 'yum list updates' ...
