This explains what multicast is: http://en.wikipedia.org/wiki/Multicast

Basically, IGMP (As mentioned in the error) as a way for a computer to say "I want to receive packets that are sent to the group xxx". The group is an IP address. In the case of your error, some device is trying to join the group "0.0.0.1" which is not a valid group.

If it's not causing any problems, I wouldn't worry about it.
