doctrine migration fails with taggable extension

When adding the Taggable behaviour to an entity, the doctrine migration fails (i'm using the symfony task) with the follwing error:

>> doctrine Migrating from version 0 to 1

The following errors occurred:

• SQLSTATE[23000]: Integrity constraint violation: 1217 Cannot delete or update a parent row: a foreign key constraint fails. Failing Query: "DROP TABLE taggable_tag"

I have a single entity in my schema, with the Taggable behavior attached:

Article:
actAs:
Taggable: ~ 
columns:
title:

{ type: string(255), notnull: true }

body:

{ type: clob }

The Version1 class which was generate by the generate-migrations-diff task looks like this:

<?php
/**

• This class has been auto-generated by the Doctrine ORM Framework
  */
  class Version1 extends Doctrine_Migration_Base
  {
  public function up() { $this->dropTable('taggable_tag'); }

public function down()

{ $this->createTable('taggable_tag', array( 'id' => array( 'type' => 'integer', 'length' => '8', 'autoincrement' => '1', 'primary' => '1', ), 'name' => array( 'unique' => '1', 'type' => 'string', 'length' => '255', ), ), array( 'type' => '', 'indexes' => array( ), 'primary' => array( 0 => 'id', ), 'collate' => '', 'charset' => '', )); }

}
