19.7.2 Unbound DNS requires forwarding

[peppersass]

After updating from 19.7.1 to 19.7.2, Unbound DNS no longer works unless I enable forwarding to DNS servers configured in System...Settings...General. Unbound DNS worked fine without forwarding before the update.

Is this related to the problem reported in this post: [RESOLVED] Force gateway broken? If so, can someone tell me how to apply the patch? And if the patch causes problems, how would I back out of it?
