Critical Error when adding the 'Cart Empty Message' element to the cart page

[lockedm]

Breakdance v2.0

When creating a Cart page and using the individual cart elements, when the 'Cart Empty Message' is added to the page, a WP Critical error is generated when you then exit from BD and go to WP. From WP, if you 'edit' the cart page you get the error as well. You can 'edit with breakdance' to get in to the page.

• start with a blank Cart Page
• add 'Cart empty message' element
• save the page
• exit to WP, you'll get the error

From WP Debug:
