lid missing in table location?

Dear webgeer

I have a strange issue: when installing Gmap I needed to maually create the table "location".
Eventually the update.php script was not able to create the table.
So I manually executed the query:

CREATE TABLE location (
        eid int unsigned NOT NULL default '0',
        type varchar(6) NOT NULL default '',
        name varchar(255) default NULL,
        street varchar(255) default NULL,
        additional varchar(255) default NULL,
        city varchar(255) default NULL,
        province varchar(16) default NULL,
        postal_code varchar(16) default NULL,
        country char(2) default NULL,
        latitude decimal(10,6) default NULL,
        longitude decimal(10,6) default NULL,
        source tinyint default '0',
        PRIMARY KEY  (type,eid)
      ) /*!40100 DEFAULT CHARACTER SET utf8 */;

Having done this Gmap does not work, and if I try to save a node with location information I am prompted with this error:
UNKNOWN COLUMN 'lid' in 'field list' query: INSERT INTO location (eid, lid, type, latitude, longitude, source) VALUES (8, 8, 'node', '45.88', '11.22', '1') in c:\programs\easyphp1-8\www\drupal_476\includes\database.mysql.inc in line 121.

As far as I know there shouldn't be any LID field in table LOCATION...
if I manually create the LID field as INTEGER everything seems to work... but I am afraid of breaking the Gmap schema...

I had the same error also with version 4.7.x-1.x, so I upgraded to 4.7.x-2.x
but with the same result.

It looks like I am the only one with this problem... can you please help?
Thank you
