Failed to update database when upgrade taxonomy_access 5.x-1.1 to 6.x-1.2.

A lot of following messages was displayed when I upgrade taxonomy_access 5.x-1.1 to 6.x-1.2

user warning: Column count doesn't match value count at row 1 query: INSERT INTO editorial_term_access_defaults (vid, rid, grant_view, grant_update, grant_delete, grant_create, grant_list) VALUES (0, $row_ints) 

I examined "taxonomy_access.install" file. It seems following code was never work. Because single quoted $row_ints value was not parsed.

38:      $row_ints = implode(", ", $row);
39:      update_sql('INSERT INTO {term_access_defaults} (vid, rid, grant_view, grant_update, grant_delete, grant_create, grant_list) VALUES (0, $row_ints)');

It's a bug?
