The GenericRelation refactoring removed GenericRelations from model._meta.many_to_many. This had the side effect of disallowing editable GenericRelations in ModelForms. Editable GenericRelations aren't officially supported, but if we don't fix this we don't offer any upgrade path for those who used the ability to set editable=True in GenericRelation subclass. Thanks to Trac alias joshcartme for the report and stephencmd and Loic for working on this issue.
