[node:content-type] no longer internal value

Hi,

I have a rule set up to display a "create another node" message to the user when a node is created. It uses the token "[node:content-type]" to link to the node/add link. this used to work. for example, if I had a content type "Useful Link" (useful-link) the message would link to "node/add/useful-link".

However, since the new version the human readable name is used instead of the machine name. So the link is now "node/add/Useful Link".

How can I link to the machine name of the content type?

Thanks
Rich
