GSets cannot be created until other items are

[Nicholas Adams]

If you have a brand new cluster with no data whatsoever, gsets cannot be created. This can currently be worked around by creating a set first and then the gset. Example underneath where I fail multiple times to create a gset, successfully create a set and then create my gset with the exact same command that was failing earlier:-

[root@localhost ~]# riak-admin bucket-type create gsets '{"props":{"datatype":"gset"}}'
RPC to 'riak@127.0.0.1' failed: {'EXIT',
                                 {badarg,

                                    [<<"gset">>,utf8],
                                    []},
                                   {riak_kv_wm_utils,erlify_bucket_prop,1,

[root@localhost ~]# riak-admin bucket-type create sets '{"props":{"datatype":"set"}}'
sets created

WARNING: After activating sets, nodes in this cluster

[root@localhost ~]# riak-admin bucket-type create gsets '{"props":{"datatype":"gset"}}'
gsets created

The above is on CentOS 6 with a vanilla install of Riak KV 2.2.6.

@Bob-The-Marauder Did anything happen with this issue? Is it still an issue?

I assume the problem is that gset is not an existing atom until the set bucket type is created ... but I don't know why it isn't, and why creating the set type makes it one.
