Order clause is broken - +options[:order]+ entry #<Origin::Key:0x00000004c1bc50...> of an unsupported object Origin::Key (ArgumentError)

[brian-thrillist]

I can't use the order clause in Zoo.all(order: [:created_at.desc]). It still works without the desc or asc bit.
Running ruby-2.2.2, data_objects (0.10.16), and datamapper (1.2.0)

Please see this stackoverflow post.

Are those the only gems? I have no idea what Origin::Key is … or where it's coming from. My guess is there might another gem that monkey-patches Symbol with methods like desc or asc and it blows away what DM does.
