Thanks for the capital letter tip!

Changing my taxonomy name to be lowercase both of my issues.

Unfortunately though, in changing the original taxonomy name, it broke my nav_menu set up that was using the same taxonomy, giving me this error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/---/---/wp-includes/formatting.php on line 445

Have investigated: this is a bug. Apparently it happens any time you change your custom taxonomy name. Some people had success deleting certain things in phpmyadmin. I decided to a fresh install.

Now everything is back to normal (minus some content that I now need to re-enter) and working perfectly.

Good luck!

Same thing is happening to me.

I have just upgraded to WP 3.1 and my custom taxonomies are no longer behaving correctly.

1. When I go to click on my custom taxonomy in the admin, I receive the WP ‘Cheatin’ uh?’ Error.

2. My WPQuery no longer filters to specific taxonomy slugs.

Registering my custom taxonomy like so:

add_action( 'init', 'build_taxonomies', 0 );
 function build_taxonomies() {
    register_taxonomy(
	    'product_Category',
	    'products',
	    array(
	        'hierarchical' => true,
	        'label' => 'Product Category',
			'public' => true
	    )
	);
}

Have been calling my query like so:

<?php $args = array( 'post_type' => 'products', 'posts_per_page' => 10, 'taxonomy' => 'private-label' ); ?>

				<?php $loop = new WP_Query( $args ); ?>
				<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

….etc…..

Anybody have any ideas what’s different about the way WP 3.1 handles custom taxonomies?
