Search Display page title is removed by ds_extras module...

Hi,

When I enable the DS Extras module and also the DS Search Display module and I put together the displays for my search results I end up with a page that has no title (h1-tag). I debugged and I found out that the problem was in the ds_extras_process_page_title() function. The first rule in that function, $page_title = drupal_static('ds_page_title');, is causing the problem. The drupal_static() function returns an empty string which is set as $variables['title'] afterwards...
How can I fix this problem?

Any help would be appreciated!
