administer blocks fails with sql duplicate key error

Installing drupal from cvs, using mysql (postgres seemed to have worse problems) and then going into the administer blocks section reports lots of:

user error: Duplicate entry '' for key 1
query: INSERT INTO blocks (module, delta, status, weight, region, path, custom) VALUES ('blog', '0', '0', '0', '0', '', '0') in /var/www/html/cvsdrupal/includes/database.mysql.inc on line 69.
user error: Duplicate entry '' for key 1
query: INSERT INTO blocks (module, delta, status, weight, region, path, custom) VALUES ('cloud', '0', '0', '0', '0', '', '0') in /var/www/html/cvsdrupal/includes/database.mysql.inc on line 69.

checking the blocks table there is only one entry and that is:

+------+---------+-------+--------+--------+--------+--------+------+--------+
| name | module  | delta | status | weight | region | remove | path | custom |
+------+---------+-------+--------+--------+--------+--------+------+--------+
|      | archive |     0 |      0 |      0 |      0 |      0 |      |      0 |
+------+---------+-------+--------+--------+--------+--------+------+--------+

This set of inserts seems to be missing the "name" column and that column (aside from being NOT NULL) is the primary key.
