Issue with user rigths

Hello. I have an issue after update from v1.6.0+rc1-97-g0cb35dd79 to v1.6.0+rc1-147-g06ef5b68d. Users who dont have site Admin rights now cannot open private organization repositories even if they are in Owner team. 404 Not Found page appears. Only after adding user as collaborator to this repository he can have rights. We have more then 50 repositories and 10 users and adding each user as collaborator to each repository is not very convenient. Is it bug or did I something wrong?
