User profile form error on ajax element with password expired

Hi,

I have a user_profile_form with custom #ajax fields. When the password_policy module sets the password expired for a user, the #ajax fields callback return an error.

Looking in password_policy module I found the function password_policy_init():

/**
 * Implements hook_init().
 */
function password_policy_init() {
  global $user;

  // Timing issues require reloading the user object
  // to get the password_change property set.
  $account = user_load($user->uid);

  // Check password reset status and force a reset if needed.
  $change_password_url = 'user/' . $account->uid . '/' . (module_exists('password_policy_password_tab') ? 'password' : 'edit/account');
  if ($account->force_password_change && $_GET['q'] != $change_password_url) {
    // let users log out
    // Marco FIX
    if (current_path() != 'user/logout') {
      drupal_set_message(t('Your password has expired. You must change your password to proceed on the site.'), 'error', FALSE);
      drupal_goto($change_password_url, array('query' => drupal_get_destination()));
    }
  }
}

As you can see, when the password is expired, the init() function redirect the user to $change_password_url if the current path is not equal to user/logout, in order to force the password change.

So what happens is that when the form ajax callback is executed on standard path system/ajax, this callback is intercepted by the init() function and not completed because of the redirect.

Fix that problem was easy for me, just replacing the 40 line with:

if (current_path() != 'user/logout' && current_path() != 'system/ajax') {

I think that this is an important issue to fix, would you like to insert the fix in the module?
