Incorrect String property :default behavior

DataMapper.setup(:default, "mysql://")
class Test
include DataMapper::Resource
property :id, Serial
property :error, String, :length => 140, :default => :null
end
DataMapper.auto_upgrade!
gives out:
CREATE TABLE IF NOT EXISTS `tests` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`error` varchar(140) DEFAULT 'null',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Why default 'null' ? not NULL

- State changed from “new” to “not-applicable”
Use :default => nil

If you don't specify anything the default :default value is nil.
I tend to encourage people to only specify options that are different from the defaults, but if you like to be explicit then solnic's suggestion is best.
