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.
