Comment (by adambackstrom):

 Here's some code that generates these errors:

 {{{
 function test_wp_update_user() {
         $userdata = array(
                 'user_login' => 'user' . md5( microtime(true) ),
                 'user_pass' => 'foo',
         );

         var_dump( wp_update_user( $userdata ) );
 }
 }}}

 And the output:

 {{{
