Set the background to a default image if there isn't a specified "featured image"

Question

I am having a little trouble displaying a default image as a background image when a feature image is not present. This is the code I am using

 <?php if (has_post_thumbnail( $post->ID ) ): ?>
 <?php $src = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), array( 5600,1000 ), false, '' );?>
 <?php else :
 $src = get_bloginfo( 'stylesheet_directory') . '/lib/images/home1-1024x681.jpg'; ?>
 <?php endif; ?>
 <section id="halfpro" style="background:url(<?php echo $src[0]; ?> ) no-repeat center center">

When I upload a feature image it works but when I do not have one selected the div is empty. When I look at the source it seems as though it is not rendering the URL correctly, I am getting this background:url(h ).

What am I missing?

I found the solution from a Wordpress forum and this is what they used. Works perfect

 <?php if (has_post_thumbnail( $post->ID ) ): ?>
 <?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), '' );
 $image = $image[0]; ?>
 <?php else :
 $image = get_bloginfo('stylesheet_directory') . '/lib/images/home1-1024x681.jpg'; ?>
 <?php endif; ?>
 <section id="halfpro" style="background-image: url('<?php echo $image; ?>')" >
