Place:
  columns:
    version:      {type: integer, length: 4}
    informations: {type: string, length: 4000}
    created_at:
  actAs:
    Versionable: # no options
    I18n:
      fields:     [ 'informations' ]

Expected generated code :

/**
 * This class has been auto-generated by the Doctrine ORM Framework
 */
abstract class BasePlace extends sfDoctrineRecord
{

	public function setTableDefinition()
	{
		$this->setTableName('place');
		$this->hasColumn('version', 'integer', 4);

		$this->hasColumn('informations', 'string', 4000);
		$this->hasColumn('created_at', '', null);




		$this->actAs('Versionable');
		$this->actAs('I18n', array(array('fields' => 'informations')));

	}

	public function setUp()
	{
		$this->hasMany('Vote', array('local' => 'id',
                               'foreign' => 'place_id'));

	}

}

What I get :

/**
 * This class has been auto-generated by the Doctrine ORM Framework
 */
abstract class BasePlace extends sfDoctrineRecord
{

	public function setTableDefinition()
	{
		$this->setTableName('place');
		$this->hasColumn('version', 'integer', 4);

		$this->hasColumn('informations', 'string', 4000);
		$this->hasColumn('created_at', '', null);




		$this->actAs('Versionable', arra));
		$this->actAs('I18n', array(array('0' => ''informations'));

	}

	public function setUp()
	{
		$this->hasMany('Vote', array('local' => 'id',
                               'foreign' => 'place_id'));

	}

}
