[Plugin: The Events Calendar] Bug with WooThemes and Fatal error

WooThemers out there beware:

The Events Calendar plugin will break your theme because of this code used in the header.php of some WooThemes.

This is the error:
Fatal error: Call to a member function get_var() on a non-object in MY SITE HIDDEN/wordpress/wp-content/themes/dailyedition/header.php on line 69

The culprit code:

<?php $cat = get_option('woo_video_category'); $GLOBALS[vid_cat] = $wpdb->get_var("SELECT term_id FROM $wpdb->terms WHERE name='$cat'"); ?>

If you’re a WooTheme user-coded there’s a fix in their forum here:

Replace with:

<?php global $wpdb; $cat = get_option('woo_video_category'); $GLOBALS[vid_cat] = $wpdb->get_var("SELECT term_id FROM $wpdb->terms WHERE name='$cat'"); ?>
