      Description

      I just did a mongodump and mongorestore and got an error:

      {{code}
      Failed: jerome5.Unit: error creating indexes for jerome5.Unit: createIndex error: Values in the index key pattern cannot be 0.
      code

      I checked on the source collection and found an index like:

      code
      {
      "key":

      { "f": 0.0 }

      ,
      "name": "f_0",
      "ns": "jerome5.Unit",
      "v": 1
      },
      code

      I'm not sure how long this has been there, but I suppose it doesn't actually do anything on the source database? Maybe it is assumed to be 1 if it's not -1 ?
