I used recursive groups once with sets, but not for enough time to
measure the performance. Do you have all needed attributes properly

Also, it's usually advised against the use of uniqueMember and
groupOfUniqueMembers for groups. Better to use groupOfNames and member
instead. But I suppose it's not related to the crash.
