sorry, I'm on leave at the moment and travelling so I'm unlikely to be
able to look at this properly.  I should be able to examine this issue
before the end of the month but cannot promise sooner than that (though
it is not impossible).

Maybe it would be best to just revert it until a proper analysis can be
done.
