The code above has some errors in it: $thisPage is used when calling bb_list_pages() recursively, but this param isn’t defined anywhere but in the function’s description… In function definition that param is instead named $parent_uri.

Moreover $kids <> "" should be replaced by !empty($kids) and I’m not sure that wordpress_mu_primary_blog_id has any meaning now that WP 3.0 has merged WP and WPMU…

Last, calling bb_list_pages() with no args, makes if ($depth == 0) true, resulting in an empty string returned. It would be good to use the same template of wp_list_pages(), which lists all pages if no param is passed to it (see docs). By the way, this could be the reason why you get nothing displayed when calling the function.
