   It's somewhat well-known how to add custom media sizes by using:
   add_image_size( HANDLE, WIDTH, HEIGHT, CROP );

   But, how to remove them? I've added a "tiny" 50x50 size and now my post-thumbnail-meta-box uses it to show the thumbnail. I only could override this by setting default thumbnail again with:
   set_post_thumbnail_size(get_option('thumbnail_size_w'), get_option('thumbnail_size_h'), get_option('thumbnail_crop'));

   Can somebody help me?

   With WordPress 3.0 out, are there any news on this subject?

   I can't find anything to specifically remove custom images sizes but you could try pulling them out of the $_wp_additional_image_sizes array :

   wp-includes/media.php:
   

   function add_image_size( $name, $width = 0, $height = 0, $crop = FALSE ) {
   	global $_wp_additional_image_sizes;
   	$_wp_additional_image_sizes[$name] = array( 'width' => absint( $width ), 'height' => absint( $height ), 'crop' => !!$crop );
   }
