 It seems the `get_post_gallery` function fails to retrieve the column
 count if it's 3.

 First, create a gallery. Then, insert 2 or 3 or any number of images and
 set its column to 3.

 Then, run this code in the context of a post (content.php / single.php
 will do):

 {{{#!php
 <?php
 $gallery = get_post_gallery( $post->ID, False );
 $gallery_images = explode( ',', $gallery['ids'] );
 var_dump( $gallery['columns'] );
 }}}

 It will come out as:


 {{{
 <b>Notice</b>:  Undefined index: columns in <b>C:\file.php</b> on line
 <b>45</b>
 }}}
