Are you using the PHP package provided by Ubuntu?  I believe that is  
PHP 5.3.10.  That is ancient.  My guess is that your PHP is too old  
(and or the libxml component) and some bug has been fixed since then  
that is the root cause of this issue for you.

FWIW, I am running PHP 5.4.22 on my system (libxml 2.9.1).
