When used in combination with the groups module and ginvite module, there is a SQL error that occurs when a person is invited to a group. When the invitation is created, user 0 is passed into the group membership creation. When a group membership is created, the group module attempts to save the anonymous user, which causes the remove_username module to copy the null value to the user name.
Whitescreen error:
