Thanks.
Well here is what kdump says happens when the index.php from Wordpress
is ran and PHP segfaults. I should probably submit this as a bug, but
I've never done that before. I'm not really sure if I'm the bug. Other
scripts, including wordpress run fine for other users. It seems to be
the latest users that can't run any scripts.
