API ver 3 bug with unscheduled features

I'm using the Pivotal API version 3 for my rails website, and when I search for features that are unscheduled / unestimated or are delivered using ActiveResource, it throws an error. Also, releases throw the same error for certain states and returns an empty array for the states that don't throw errors. Here is the script console output for unscheduled features:

>> Story.find(:all, :params => {:filter => "type:Feature state:unscheduled", :project_id => pivotal_project_id})
