In your original node, you only actual show a couple of modules being used:

use strict;
use XML::Simpl­e;
[download]

I wasn't thinking the problem was due to strict.pm changes.

I believe the data structure that is no longer in the same shape that it used to be in is one being generated by that other module.

You might want to compare the version numbers of that module and even read the Changes file for that module.
