      For reference when reading the following: a Ruby symbol is represented in the form :symbol and is serialized to the BSON Symbol type.
      Using the most recent Ruby driver (1.12.0.rc0), with MongoDB server version 2.6:

      client = MongoClient.new
db = client['test']
db.create_collection(:foo)
db.drop_collection(:foo)
=> true

      This is what mongosniff shows:

      127.0.0.1:56381  -->> 127.0.0.1:27017 admin.$cmd  58 bytes  id:e	14
	query: { drop: "foo" }  ntoreturn: -1 ntoskip: 0
127.0.0.1:27017  <<--  127.0.0.1:56381   88 bytes  id:f	15 - 14
	reply n:1 cursorId: 0
	{ ns: "admin.foo", nIndexesWas: 1, ok: 1.0 }
 

      With MongoDB nightly Nov-18-2014 and the most recent Ruby driver (1.12.0.rc0):

      client = MongoClient.new
db = client['test']
db.create_collection(:foo)
db.drop_collection(:foo)
=> false

      And this is the mongosniff output

      127.0.0.1:56381  -->> 127.0.0.1:27017 admin.$cmd  58 bytes  id:13	19
	query: { drop: "foo" }  ntoreturn: -1 ntoskip: 0
127.0.0.1:27017  <<--  127.0.0.1:56381   94 bytes  id:14	20 - 19
	reply n:1 cursorId: 0
	{ ok: 0.0, errmsg: "no collection name specified" }

      In looking at the commit that changed this behavior, other commands are probably affected as well.

      The server no longer accepts the Symbol BSON type for some command values. In particular, the 'drop' command is affected.

      I believe it is because of this commit https://github.com/mongodb/mongo/commit/d41f98bd0fdc3d392fc19aadfdc62a020d17fede
