DQL Query with key=>value array in parameter

In he method "processParameterValue" in the class Doctrine\ORM\Query line 303, a "for" loop is use for construct the parameter query.

But if in the query parameter we pass a key=>value array, the method throw an error.

A little example :
$aId = array(0 => "Paris", 3 => "Canne", 9 => "St Julien");

$dql = $this->_em->createQueryBuilder();
$dql->select('c.ID')
->from('BOD\ModelBundle\Entity\City', 'c')
->where('c.IC IN (:cityIDs)')
->setParameter('cityIDs', $aId);

return $dql->getQuery()->execute();

The method "processParameterValue" throw an error because he don't found the index 1.

But if we replace the "for" loop by a foreach in Doctrine\ORM\Query::processParameterValue() :
foreach ($value as $keyValue => $oneValue) {
$paramValue = $this->processParameterValue($oneValue);

// TODO: What about Entities that have composite primary key?
$value[$keyValue] = is_array($paramValue) ? $paramValue[key($paramValue)] : $paramValue;
}

It work really fine.

I remain at your disposal for any further information.

Thanks for all!
