Definition of array in hook_block_info

Once I have installed and configured this module, I found a trouble to enable its block.

I think that the problem is in the index of the array blocks, after I changed it, I resolved this issue, below the changes that I've made:

function tagadelic_block_info() {
  $blocks = array();
  foreach (taxonomy_get_vocabularies() as $voc) {
    $blocks['tag_'.$voc->vid] = array();
    $blocks['tag_'.$voc->vid]['info'] = variable_get('tagadelic_block_title_' . $voc->vid, t('Tags in @voc', array('@voc' => $voc->name)));
    $blocks['tag_'.$voc->vid]['cache'] = DRUPAL_CACHE_GLOBAL;
  }
  return $blocks;
}
