Custom taxonomies generating invalid argument error (I think)

I’ve been developing a theme locally and having everything work just peachy. However, when I pushed the theme to a testing server today, I got the following error:

Warning: Invalid argument supplied for foreach() in /home/theem3/theemerson.org/wp-includes/post.php on line 1038

I looked into that file and found that it is the following function:

foreach ( $args->taxonomies as $taxonomy ) {
		register_taxonomy_for_object_type( $taxonomy, $post_type );
	}

This leads me to believe that I’ve done something weird when creating my custom taxonomy or custom post types. But, I followed the directions here to a T. Here’s my code that I’m working with.

add_action( 'init', 'register_events' );
function register_events() {
	$labels = array(
		'name' => 'Events',
		'singular_name' => 'Event',
		'add_new' => 'Add New Event',
		'add_new_item' => 'Add New Event',
		'edit' => 'Edit Event',
		'edit_item' => 'Edit Event',
		'view' => 'View Event',
		'view_item' => 'View Event',
		'search_items' => 'Search Events',
		'not_found' => 'No Events found',
		'not_found_in_trash' => 'No Events found in Trash',
	);
	$args = array (
		'labels' => $labels,
		'description' => 'Events custom post type',
		'show_ul' => true,
		'menu-position' => 5,
		'exlude_from_search' => false,
		'hierarchical' => true,
		'menu_icon' => get_stylesheet_directory_uri() . '/images/calendar-icon.png',
		'supports' => array('title','editor','thumbnail'),
		'public' => true,
		'rewrite' => array('slug' => 'event', 'with_front' => false),
		'taxonomies' => array('post_tag', 'category')
	);
	register_post_type ('event', $args);
}

add_action( 'init', 'register_features' );

function register_features() {
	$labels = array(
		'name' => 'Features',
		'singular_name' => 'Feature',
		'add_new' => 'Add New Feature',
		'add_new_item' => 'Add New Feature',
		'edit' => 'Edit Feature',
		'edit_item' => 'Edit Feature',
		'view' => 'View Feature',
		'view_item' => 'View Feature',
		'search_items' => 'Search Features',
		'not_found' => 'No Features found',
		'not_found_in_trash' => 'No Features found in Trash',
	);
	$args = array (
		'labels' => $labels,
		'description' => 'Features custom post type',
		'show_ul' => true,
		'menu-position' => 5,
		'exlude_from_search' => false,
		'hierarchical' => false,
		'menu_icon' => get_stylesheet_directory_uri() . '/images/feature-icon.png',
		'supports' => array('title','editor','thumbnail','custom-fields'),
		'public' => true,
		'rewrite' => array('slug' => 'features', 'with_front' => false),
		'taxonomies' => array('feature-type', 'post_tag')
	);
	register_post_type ('feature', $args);
}

add_action( 'init', 'create_feature_taxonomies', 0 );

function create_feature_taxonomies() {
	// Add new taxonomy, make it hierarchical (like categories)
	$labels = array(
		'name' => _x( 'Feature Types', 'taxonomy general name' ),
		'singular_name' => _x( 'Feature Type', 'taxonomy singular name' ),
		'search_items' =>  __( 'Search Feature Types' ),
		'all_items' => __( 'All Feature Types' ),
		'parent_item' => __( 'Parent Feature Type' ),
		'parent_item_colon' => __( 'Parent Feature Type:' ),
		'edit_item' => __( 'Edit Feature Type' ),
		'update_item' => __( 'Update Feature Type' ),
		'add_new_item' => __( 'Add New Feature Type' ),
		'new_item_name' => __( 'New Feature Type' ),
	); 	

	register_taxonomy( 'feature-type', array( 'feature' ), array(
		'hierarchical' => true,
		'labels' => $labels,
		'show_ui' => true,
		'query_var' => true,
		'rewrite' => array( 'slug' => 'feature-type' ),
	));
}

add_action( 'init', 'register_slides' );
function register_slides() {
	$labels = array(
		'name' => 'Home Slides',
		'singular_name' => 'Home Slide',
		'add_new' => 'Add New Home Slide',
		'add_new_item' => 'Add New Home Slide',
		'edit' => 'Edit Home Slide',
		'edit_item' => 'Edit Home Slide',
		'view' => 'View Home Slide',
		'view_item' => 'View Home Slide',
		'search_items' => 'Search Home Slides',
		'not_found' => 'No Home Slides found',
		'not_found_in_trash' => 'No Home Slides found in Trash',
	);
	$args = array (
		'labels' => $labels,
		'description' => 'Home Page Slides custom post type',
		'show_ul' => true,
		'menu-position' => 5,
		'exlude_from_search' => false,
		'hierarchical' => false,
		'menu_icon' => get_stylesheet_directory_uri() . '/images/slide-icon.png',
		'supports' => array('title','thumbnail', 'custom-fields'),
		'public' => true,
		'taxonomies' => ''
	);
	register_post_type ('slide', $args);
}

If anybody could take a look and see if anything looks weird, I would certainly appreciate it. Removing all creation of custom post types clears the error, but unfortunately, that’s not really an option. Any suggestions?
