Chris, can you post your complete clusterstate.json? Do all shards have a null range? Also, did you issue any core admin CREATE commands apart from the create collection api.
Primoz, I was able to reproduce this but by doing an illegal operation. Suppose I create a collection with numShards=5 and then I issue a core admin create command such as: http://localhost:8983/solr/admin/cores?action=CREATE&name=xyz&collection=mycollection51&shard=shard6 Then a "shard6" is added to the collection with a null range. This is a bug because we should never allow such a core admin create to succeed anyway. I'll open an issue.
