apache2 coredump после включения mod_pagespeed в CentOS

Я пытаюсь заставить следующие модули apache2.2 работать вместе mod_pagespeed, mod_spdy и плагин WebSphere Webserver на CentOS.

Как только mod_pagespeed изменяет путь к файлу, браузер больше не может разрешить этот файл. У меня есть coredump, но я не знаю, как это читать:
