NetworkManager crashed with SIGSEGV in nm_dhcp_dhclient_escape_duid()

I wasn't aware of changing the .conf file that it said I changed, but the computer froze upon starting it, so I did a hard reset, and it wasn't able to connect to a network via wireless before logging in (like it usually does). It's doing fine right now, but I think that might be what this is about.
