Upgraded to 2.8.2, “get_categories” not working…

I just upgraded to WordPress 2.8.2 and this piece of code in my theme is no longer working…

<ul id="prodCats">
<?php
$categories = get_categories('orderby=order');
foreach ($categories as $cat) {
	if ($cat->category_nicename != 'general') {
		if ($cat->category_parent == 0) { ?>
			<li><a href="<?php echo get_option('home');?>/products/#<?php echo $cat->category_nicename; ?>">
				<img src="<?php echo get_option('home');?>/catImgs/<?php echo $cat->category_nicename; ?>.jpg" />
				<p class="catName"><?php echo $cat->cat_name; ?></p>
			</a></li>
<?php 	}
	}
} ?>
</ul>
