This bug also affects our boxes that have network-manager 1.2.6-0ubuntu0.16.0 amd64. Can confirm that one of our boxes, which is still on 14.04 LTS, and has network-manager 0.9.8.8-0ubuntu7.3 amd64 does not have these issues.

In our case, we noticed that, when VPN is active, network-manager refuses to use the DNS servers defined by the VPN (openVPN). In stead, network-manager defaults to the "normal", "local" DNS server.
This means a DNS leak, since the original (ISP) DNS can be seen.

A workaround is setting 'Automatic (DHCP) addresses only" under IPv4 Settings in network-manager for the default network connection. This means however that, when no VPN, but the default net connection is used, network-manager has no DNS server, because this has to be entered manually in the DNS Servers field.
