If I enter a badly formed url for the pageset, I get this error message:

I'd like the default behaviour for this error to be 'reload last working version' (or/and the default setting) because at the moment a user can end up in an unrecoverable situation. (they put in a badly formed url and don't have the old one around to replace it).
