Notice: Undefined variable: themed_regions in zeropoint_preprocess_block()

After enabling the theme I get the following message:

Notice: Undefined variable: themed_regions in zeropoint_preprocess_block() (line 148 of [...]/sites/all/themes/zeropoint/template.php).

Do not have time for creating a patch, but this can be easily fixed with adding an extra check to the line 148:

  if ($themedblocks == '1'){
    $themed_regions = array('sidebar_first','sidebar_second','user1','user2','user3','user4','user5','user6','user7','user8');
  }
  if (isset($themed_regions) && is_array($themed_regions))
    $vars['themed_block'] = (in_array($vars['block']->region, $themed_regions)) ? TRUE : FALSE;
  else $vars['themed_block'] = FALSE;
