"Invalid argument" Message -After WPMU DEV Dashboard Update

After the "WPMU DEV Dashboard" Update I briefly got the message,

Warning: Invalid argument supplied for foreach() in /home/**Name_detracted**/public_html/wp-content/plugins/wpmudev-updates/update-notifications.php on line 1662

Which is the dashboards "Page Output Function". The message went away, but might be worth a look. Thanks.
