OpenID Plugin (WP 2.5) calls non-existant error() method.

This bit of code in logic.php fails:

if( ! wp_login( $user->user_login, md5($user->user_pass), true ) ) {
					$this->error = 'User was created fine, but wp_login() for the new user failed. '
						. 'This is probably a bug.';
					$this->action= 'error';
					$this->core->log->error( $this->error );
					break;
				}

Do I need to enter a password in the password box? This should be described above the input text box for the OpenID URL.
