There is an error being thrown with WP_DEBUG on: Uninitialized string offset.
I believe this is due to how PHP is interpreting the data type in this array, but if you add the following line to wp-quick-deploy.class.php and comment out the old line 420, it should be fixed:
if (substr($val, 0, 1) == "-") //error fix, Line 420, wp-quick-deploy.class.php
//if ($val[0]=="-")
