Reference to NULL in "query" function of "wp-db.php" file leads to incomplete installation

[Nima Dezhkam]

When installing WordPress 1.5.2 (MySQL 4.0.24 and PHP 5.0.4), call of function "upgrade_all" in "install.php" and the consequent function calls lead to a reference to NULL in the "query" function in "wp-db.php". So that, although the success email with username/password is sent to the user, the installation is not complete, and login page appears to be blank. The line referencing to NULL is:

$this->col_info[$i] = @mysql_fetch_field($this->result);

So I put a check before this line. The new code is:

if($this->col_info){
    $this->col_info[$i] = @mysql_fetch_field($this->result);
}

Changing to minor as it obviously doesn't happen for the large majority of people
