Attached to this email is one (admittedly crude) patch that passes the two new testcases (and one additional case with the link at the feed level and not the item level). The patch also fixes a regression from the 2006 vulnerability (htmlToText *must*  always be entity encoded afterwards). 

This patch is *not* a long term solution (i.e. it doesn't do whitelist HTML filtering instead of blacklist or drop privileges in any form).

I'll liaise with the security team about making uploads now.
