Fantastic - thanks for your explanation and the SRPM James. For the record,
James appears to be completely correct and his SRPM fixes my problems here
on CentOS 4.5 - woohoo!

His patch also applies cleanly to the current CentOS 5 package and fixes 
the problem there as well - a patched SRPM is available here for anyone else
experiencing the problem:

(and binary packages are in http://www.openfusion.com.au/mrepo/).
