question about php5-ps

[Ray]

Hello,
I am trying to use the package php5-ps (version 1.3.6-7build1, amd64) with 
php5.4 (php5.4.6-1ubuntu1.1, amd64) both from the quantal repositories. 
(system is running kubuntu 12.10 amd64) Scripts using this functionality are 
seg faulting and dumping core (even sample code written by the original 
author). The source code contains incompatibilities with php 5.4 and I am 
wondering if this is a symptom of being built on a system that wasn't using 
php 5.4, or if there is another problem as well. 
I'd be happy to provide any useful information.
Any suggestions appreciated.
Ray
