hook_civicrm_post function called with 'edit' operation when creating a new Individual

When creating a new contact via Drupal's register function the hook_civicrm_post() function call for the Individual is called with 'edit' operation when it should be a 'create' function. The hook_civicrm_pre() function is called correctly.

Can be reproduced with a simple drupal module with the _civicrm_pre() and _civicrm_post() functions and log the calls. When creating a new account in Drupal the following is called (in order):

function operation objectName
-----------------------------------------
_civicrm_validate
_civicrm_pre create Profile
_civicrm_pre create Individual
_civicrm_post edit Individual
_civicrm_post create Profile
_civicrm_validate
_civicrm_pre edit Profile
_civicrm_pre edit Individual
_civicrm_post edit Individual
_civicrm_post edit Profile
