Autocomplete starting with . broke after drupal update > 7.38

Normally, when you input a . on a autocomplete textfield, you get the most used references,
since the core update of 7.39 this functionality broke.

In the includes/form.inc there was a change on line 4013 from:

$attributes['value'] = url($element['#autocomplete_path'], array('absolute' => TRUE));

to:

$attributes['value'] = $element['#autocomplete_input']['#url_value'];
