Binary package hint: network-manager

I am using Network Manager to connect to my OpenVPN server. When I use
the openvpn command line client, DNS push is fine,  resolv.conf is
updated to the pushed DNS servers (old lines gone). When I use NM,
resolv.conf is not written corretly. The OpenVPN server pushes 4 DNS
server, but only the first one is appended to resolv.conf. It should
remove the old lines and add the 4 servers from the OpenVPN server to
resolv.conf.

My daemon.log after connecting:
