Please, disable the php-java-bridge thing (p.masked now anyway) and try again.

[Comment 5 Ivan Yarych 2008-11-14 14:19:45 UTC]

I have the same problem. I have never noticed it before I installed Joomla (not from Portage, but manually) - it sometimes segfaults showing strange errors, sometimes empty page and sometimes works.
