I had a similar problem and have implemented a workaround for now by taking out the set password and saving then setting the password with the login library.

PHP Code:

$loginlib = vB_Library::instance('login');             
$loginlib->setPassword($newuserid, $password, array('passwordhistorylength' => $passwordhistorylength)
); 


But I would be interested in how you are supposed to use the dm with 5.1.0
