Theme fails on custom post types w/o a category

Hello,
I am a plugin developer and one of my customers contacted me about the plugin not working with this theme. I investigated the problem and discovered theme was throwing the following error:

• PHP Notice: Undefined offset: 0 in \wp-content\themes\simplenotes\functions.php on line 119
• PHP Notice: Trying to get property of non-object in \wp-content\themes\simplenotes\functions.php on line 119
• PHP Catchable fatal error: Object of class WP_Error could not be converted to string in \wp-content\themes\simplenotes\functions.php on line 120

I looked into the code on these lines and saw that this theme assumes there will be a category assigned if the user is viewing a single post. My plugin uses custom post types and does not use the WP categories. A simple if-statement solves the problem by checking to see if the post does indeed have a category before trying to use it:

$category = get_the_category();
if ( count($category) > 0 ) {
       $category_id = get_cat_ID( $category[0]->cat_name );
       echo '<li> &nbsp; ► '. get_category_parents( $category_id, TRUE, "</li><li> &nbsp; ► " );
} else {
	echo "<li> &nbsp; ► ";
}
echo the_title('','', FALSE) ."</li>";
