Can't convert nil into Hash when using a type from dm-types

[spockz]

When using a type from dm-types in migrations I get the following error: can't convert nil into Hash when running rake db:migrate. This is a rails project. Is it maybe related to #31, which is already closed?

The migration:

migration 1, :foo do
  up do
    create_table :rekenservices do
      column :id, DataMapper::Property::Serial, :key => true
      column :webaddress,       URI,     :required => true
    end
  end
end
