Segfault when procesing a command with empty namespace

A simple program that can make the mongod server crash:

string errMsg;

DBClientConnection conn;

conn.connect( "localhost:27017", errMsg );

BSONObj result;

conn.runCommand( "", BSON( "count" << "" ), result );

Note: v2.0.4 handles this gracefully by throwing the assertion: "User Assertion: 13074:db name can't be empty"
