Result summary in views header only shows up if a pager is present

The problem is this row:

$total =$this->view->total_rows;
...
    if (!empty($total)) {
      $output .= filter_xss_admin(str_replace(array_keys($replacements), array_values($replacements), $format));
    }

As you see if total_rows will not be set, it simply doesn't display something. For some pager plugins though there is no count query runned, and so total_rows is not set. Here is a patch

Thanks for the bug report and testing the patch! Committed to 7.x-3.x

Maybe this could be backported to 6.x-3.x

Works for me too! However I was hoping that $total would be the actual total in the database, not what was queried, i.e. if "Use pager: Display a specified number of items | 5 items" then $total will just be 5 items...

This may be nit-picking, but
$total = isset($this->view->total_rows) ? $this->view->total_rows : count($this->view->result);
can just be
$total = isset($this->view->total_rows) ? $this->view->total_rows : $count;

($count was defined on line 63 but I don't see it being used anywhere else)

Here's a patch for the 6.x-2.x branch, incase anyone else needs it.

Patch in comment #5 applies without difficulty to latest views-6.x-2.26 and is a simple patch that was committed to views-7.x-3.x.
I have reviewed it and am marking it RTBC for 6.x-2.x
