Что не так с моим громадным .htaccess?

Смотрите, какая красота хорошо чувствовала себя на домашнем Денвере:

После залива на хостинг, вылезла 500-ая ошибка. Методом тыка был вычислен тот кусок «.htaccess», который её вызывал:

Пока что оставил весь «.htaccess» с закомментированным проблемным куском. Всё нормально работает, но паранойя не отпускает. Что в нём не то?
