REPLACES].

the solution is trivial but took me a few hours to pickup the patch is a
patch against clean 1.4.24.1.

Ok since this patch has gone live no problems to report.

this only affected a small % of customers in total about 6 sites were
affected.

there have been no other issues related to this patch rolled out to about
80 installs directly managed by us.

i certainly would recommend inclusion in 1.4.25, we adopted 1.4.24 late
and thus a delay in picking up this problem.
