When using Zend_CodeGenerator_Php_Property_DefaultValue and setting a multidimensional array as the value and setting Zend_CodeGenerator_Php_Property_DefaultValue::TYPE_ARRAY as type i get:

Fatal error: Call to a member function setArrayDepth() on a non-object in /home/developer/projects/zftrunk/library/Zend/CodeGenerator/Php/Property/DefaultValue.php on line 294

Based on this i wrote an additional unittest to show this behavior

public function testPropertyDefaultValueCanHandleMultidimensionalArray()
{
    $propDefaultValue = new Zend_CodeGenerator_Php_Property_DefaultValue();
    $propDefaultValue->setValue(array('foo' => array('bar' => 'baz'), 'bar' => array('foo' => 'baz')));
    $expected = 'array(
    \'foo\' => array(\'bar\' => \'baz\'),
    \'bar\' => array(\'foo\' => \'baz\')
    );';
    $this->assertEquals($expected, $propDefaultValue->generate());
    $propDefaultValue->setType(Zend_CodeGenerator_Php_Property_DefaultValue::TYPE_ARRAY);
    $this->assertEquals($expected, $propDefaultValue->generate());
}

The first assertion works fine as TYPE_AUTO is used and a special handling for TYPE_ARRAY is then activated. (DefaultValue.php line 243) The second assertion dies with mentioned error.
