The module calls json_decode, which is only available in php > 5.2.
This should be documented (or include alternative code)

Title: Module requires php 5.2 » Module requires JSON extension
Status: Active » Fixed

I've added a statement to this module's project page that it requires the JSON extension, which is included in PHP 5.2 or can be installed as a separate extension.
