drupal/civicrm.module::civicrm_block('list',...) returns wrong format

In CiviCRM 2.1-alpha-4 on Drupal 6.4, the admin/build/block page has a problem showing information about CiviCRM blocks because the returned value goes an array too far. The fix is to replace line 159 of that file with:

$crm_blocks = CRM_Core_Block::getInfo();
foreach ($crm_blocks as $crm_block)

{ $block[] = $crm_block['info']; }
