WordPress MU

Hello,
I have created a php page that reads a CSV file(user, pass, mail), and creates X users and blogs.
1- Reading the CSV:

$i = 0;

while (($data = fgetcsv($csv, 200, ",")) !== FALSE) {

  $user[$i] = $data[0];
  $pass[$i] = $data[1];
  $mail[$i] = $data[2];
  $i++;

}

fclose($csv);

2- Creation of multiple users:

$domain = 'domaine.com';
$meta = '';

$z = 0;

while ($z < $i) {
  $path = '/'.$user[$z];
  $title =  $user[$z];
  $u = wpmu_create_user($user[$z], $pass[$z], $mail[$z]);
  sleep(3);
  $b = wpmu_create_blog($domain, $path, $title, $u, $meta, $wpdb->siteid);
  sleep(3);
  $z++;
}

So all the users and blogs get created / installed, but only the first blog in the loop has its DB Tables created.
And for the rest of the blogs i get an error:

The blog you have requested is not installed properly. Please contact the system administrator.

When i check my database, there are only tables for the FIRST user:
wp_24_comments
wp_24_links
wp_24_options
wp_24_postmeta
wp_24_posts
wp_24_terms
wp_24_term_relationships
wp_24_term_taxonomy

My issue is exactly this http://trac.mu.wordpress.org/ticket/394

Thanks in advance.

I'm having the same problem. I also found that bug. Even after applying the patch, the bug persists in the latest version.

Spotted that myself and didn't have time to find the problem. In the end I just had the page create a single blog, then put some javascript in the footer to reload itself and thus create the next blog.

Not nice, neat or efficient, but I only had a few to create so it did for the time being.

I'm having the same problem!
