Broadcast permission is assigned to authenticated users, but only administrator can broadcast

I did a little investigation in the code using xdebug, in og_perm_check_access() function :

function og_perm_check_access() {
  $args = func_get_args();
  // Permission is the last argument.
  $perm = array_pop($args);
  // Callback is one argument before the last one.
  $callback = array_pop($args);
  return call_user_func_array($callback, $args) && user_access($perm);
}

$callback is 'og_broadcast_access' which returns 0, so no matter what user_access() returns 'broadcast message to group' permission is denied.

I think this is a bug and the last line of the function should be changed to :

return call_user_func_array($callback, $args) || user_access($perm);
