Strange arrays being output on front-end instead of website

Question

Trying to setup version control on a pre-existing client's site. There have been a number of developers who have had their hands in this and I'm slowly modifying the .gitignore file in attempt to bring over all the necessary files. It's a real mess but somehow running in production. :D

I'm currently getting an array output on my front-end that is something like this repeated about 50 times on my local environment:

Array ( [0] => Array ( [file] => /Users/deeperdata/Documents/webroot/website/lib/Zend/Db/Adapter/Pdo/Mysql.php [line] => 96 [function] => _connect [class] => Zend_Db_Adapter_Pdo_Abstract [type] => -> [args] => Array ( ) ) [1] => Array ( [file] => 

I checked Apache, PHP and Magento logs. I'm showing nothing. Any ideas?
