Search sending empty Parameter to Filter

Hi there,

I am using custom post types to show attendees for events. As my attendees also have their customers, I am filtering them by event and customer including some self-made adjustments. Recently installed Search Everything-Plugin to search for my custom post types.
Now I have some curious problem:
At the BE I see my filter-dropdowns and the search-input field. With adjusting my filters, the whole form is submitted, including the “empty” input field, sending “s” as GET-Parameter. Unfortunately the Parameter is empty and I do not see any results. I have to submit the form one more time and I see the correct result.
I was looking around at the “core” of Search Everything-Plugin and found a place where “s” is not checked if empty. Just added one line of code and now it works as expected:
search-everything.php, line 248.

if(empty($this->query_instance->query_vars['s']))
			return $where;

Maybe someone can just add it to the repository? Can’t see any error or mistake, while I shouldn’t check the var there as well ??

Greetings
