taxonomy term 0 not showing

When you edit a node and display the "Block Taxonomy Settings", the first term is not showing.. the listing starts from 1 instead of 0.

To make it work, I had to comment out this line 67 of blockterm.module:
vocab_select['#options'] = is_string($vocab_select['#options']["0"]) ? $vocab_select['#options'] : array(0 => theme('none_option')) + $vocab_select['#options'];
