panic reading index

[Nick Stott]

Hi All,

I'm getting a panic reading an index using mgo, go1.1, on a recent osx.

when I add an index via the mongo cli as follows,

pantstastic:PRIMARY> db.foo.ensureIndex({whoop:1})
pantstastic:PRIMARY> db.foo.getIndexes()
[
 {
  "v" : 1,
  "key" : {
   "_id" : 1
  },
  "ns" : "test.foo",
  "name" : "_id_"
 },
 {
  "v" : 1,
  "key" : {
   "whoop" : 1
  },
  "ns" : "test.foo",
  "name" : "whoop_1"
 }
]

and then read the index by:

indexes, err := sess.DB("test").C("foo").Indexes()

I get a panic: Got unknown index key type for field whoop

It seems that for some reason, the function simpleIndexKey in mgo's session.go expects the key to have a value that's either an integer or a string. on my system, realKey[i].Value seems to think that it's a float64
