Can't use the user register service with logintoboggan module

This is kind of a blocker as i can't use this module with services 3.
when i call the user/register built in service the services function builds a form data object and tries to submit it, in this process the following code is running:

// register a new user
  $form_state['values'] = $account;
  $form_state['values']['pass'] = array(
    'pass1' => $account['pass'],
    'pass2' => $account['pass'],
  );
  $form_state['values']['op'] = variable_get('services_user_create_button_resource_create', t('Create new account'));

  // execute the register form
  drupal_form_submit('user_register_form', $form_state);

in the process of validating the user password, logintoboggan calls the function logintoboggan_validate_pass and runs the following code:
if (!strlen($pass)) return t('You must enter a password.');

as you can see using this module i will never be able to get over this.
logintoboggan needs to be aware of this behavior and support it.

Thanks
