Public bug reported:
According to syslog, dhcp-server sends:
address 10.0.0.123/24
classless static route 10.0.0.138/32 gw 10.0.0.2
classless static route 10.0.0.0/24 gw 0.0.0.0
classless static route 192.168.13.0/24 gw 0.0.0.0
gateway 10.0.0.1
but the host-route to 10.0.0.138 is not found in routing table.
a packet-sniff with wireshark confirms, that syslog of NetworkManager
indeed reflects what the dhcp-server was sending.

Note, that the route to 10.0.0.138/32 specified by dhcp-server is
missing and should have been added to routing-table by network-manager.
adding the route manually is possible:
$ sudo route add 10.0.0.138/32 gw 10.0.0.2
