civicrm_admin_menu called from uninitialized path

In CiviCRM 2.1-alpha-4 with Drupal 6.4 and admin_menu.module 6.x-1.0, the civicrm_admin_menu() hook function is called from a path that has not previously called civicrm_initialize(), causing severe lossage. The fix is to add the lines indicated below to drupal/civicrm.module:

function civicrm_admin_menu( ) {
+ // make sure the system is initialized
+ if ( ! civicrm_initialize( ) )

{ + return; + }

+
+ $config =& CRM_Core_Config::singleton();
