Numeric terms facet yields redundant "0.0" buckets when mincount and sort specified

This query:

http://localhost:8983/solr/techproducts/select?q=*:*&json={"facet":{"price":

{"type":"terms","field":"price","sort":"index asc","mincount":0}

}}&wt=json

Yields results where every bucket has value "0.0" and count "0". Dropping either the "mincount" parameter or "sort" parameter fixes it.

This is using nightly build 5.3.0-2015-05-29_12-15-41 1682437 - jenkins - 2015-05-29 08:22:15. Apologies if this has been fixed since.
