I have experienced the same bug on multiple brands of NIC hardware both wired and wireless. Observing the live log, it always occurs 30 minutes after boot. My DHCP server renews leases after an hour so I did not see a correlation with the network configuration.
Googling this error reveals similar issues across several major distros so this may be an upstream bug.
My early Virtualbox tests did not show an issue with a bridged adapter. Re-running those tests again to verify.
I also disabled Avahi-daemon in a troubleshooting attempt and NM still failed with the same error.
