Trouble with 1.7.2 and i18n behaviour

[shodanto]

Since 1.7.2 i am having trouble with the i18n behaviour. It changed and doesn't deliver the proper language object.
Code:

CategoryQuery::Create()->joinWithI18n(getLocale())->filterByIsMenu(true)->filterByParentId($category->getCategoryId())->useCategoryI18nQuery()->filterByIsactive(true)->enduse()->orderBySort()->find()

Executed query 1.7.1:
SELECT .. FROM categoryLEFT JOINcategory_i18nON (category.categoryId=category_i18n.categoryId AND category_i18n.locale = 'de_DE') WHERE category.isMenu=1 AND category.parentId_second=5 AND category_i18n.isActive=1 ORDER BY category.sort_second ASC;

Executed query 1.7.2:
SELECT ... FROM categoryLEFT JOINcategory_i18nON (category.categoryId=category_i18n.categoryId) WHERE category.isMenu=1 AND category.parentId=10 AND category_i18n.isActive=1 ORDER BY category.sort ASC;

The Problem lies in class Join.php line 580;

 return $join !== null
            && $join instanceof Join
            && $this->getJoinType() == $join->getJoinType()
            && $this->getConditions() == $join->getConditions()
            **&& $this->getClause($parametersOfThisClauses) == $join-> >getClause($parametersOfJoinClauses);** //this line has been added
}
