CRM-12272 Fixed logic so that form rule ensures that EITHER custom_pre OR custom_post is an individual profile. Previously the code was throwing form rule error when custom_post was NOT type individual even though custom_pre was. However, the complete fix is to check for first + last name profile fields when Allow multiple registrations from same email is checked. Will file issue for that for 4.4.
