It's much more likely that this is due to the update of dnsmasq (https://launchpad.net/ubuntu/+source/dnsmasq/2.73-1):

juin 30 09:51:14 u32 NetworkManager[812]: <warn> dnsmasq not available on the bus, can't update servers.
juin 30 09:51:14 u32 NetworkManager[812]: <error> [1435650674.886674] [dns-manager/nm-dns-dnsmasq.c:398] update(): dnsmasq owner not found on bus: Could not get owner of name 'org.freedesktop.NetworkManager.dnsmasq': no such name
juin 30 09:51:14 u32 NetworkManager[812]: <warn> DNS: plugin dnsmasq update failed

Can you please test downgrading dnsmasq-base to the previous version https://launchpad.net/ubuntu/+source/dnsmasq/2.72-3.1build1 ? If that works, then it's a dnsmasq regression, or NetworkManager needs to get adjusted to the newer version.

If that doesn't work, can you please try to downgrade to the previous systemd version? This is much less likely to work as systemd doesn't do any network configuration beyond starting NetworkManager (which obviously works) and calling ifupdown (which you don't seem to use).
