With the current behavior, insert-buckets doesn't automatically allocate non-overlapping bucket ids. This could be considered a bug in the documentation or in the code. It would be more user-friendly to consider a bug in the code and fix it in ovs-ofctl, but that's a bigger job than just fixing the crash as these commits do.
