      java.lang.NullPointerException
	at com.mongodb.DBTCPConnector._error(DBTCPConnector.java:287)

      The _error method doesn't count that _rsStatus might be null.

          boolean _error( Throwable t, boolean slaveOk )
        throws MongoException {
        if ( _rsStatus.hasServerUp() ){
            // the replset has at least 1 server up, try to see if should switch master
            checkMaster( true , !slaveOk );
        }
        return _rsStatus.hasServerUp();
    }
