I was the same, the message appears if there are no required fields in the multigroup ... I have placed a required field inside multigroup and the warnings no longer jumps.

You can see http://drupal.org/node/1097548 if you need more help, they have talked for a while about this problem, good luck.

Hey,
I had fixed this warning with this one file or this listed patch. This is the patch corrected file you just have to replace with this one. It works good and tested.
Or
You can make patch file with replacing this one
