Error when trying to get the columns of a three-columns gallery.

[virginthumb]

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
$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>

Big update.

Turns out this bug only happens when there are 2 galleries. Removing the second gallery fixes it, but still, get_post_gallery should get the first / "featured" gallery only.
