Acts_as_List in :scope Interning in Edge

Has something changed with how Acts_as_List interpolates the :scope
parameter in Edge? I'm finding that a :scope condition like

'album_id = #{album_id} AND parent_id IS NULL'

is being interpolated into

SELECT * FROM photos WHERE (album_id = AND parent_id IS NULL)

I know for sure album_id is being during the save process.

Any one have any clues?

the model Photo must have a attribute named album_id

It does.
