A strange issue with graphene.js and slider background images

Hi,

I have some sort of problem with “Preload slider background images” property located in graphene.js.

When I followed from the chrome developer tools/source, I get the “Failed to load resource: the server responded with a status of 404 (Not Found) https://ee.yeditepe.edu.tr/tr/%5Bobject%20HTMLDivElement%5D” message and website load effected by about 2sec.

And when I click on the problem from developer tools it points out the “(new Image()).src = this;” line from below code.

// Preload slider background images
		if ( grapheneJS.sliderDisplay == 'bgimage-excerpt' ) {
			$('.slider_items .slider_post').each(function(){
				var src = $(this).css('background-image').replace('url(', '').replace(')','');
				if ( src.indexOf('http') == 0 ){
					(new Image()).src = this;
				}
				src = null;
			});
		}

Also I followed the site loading from tools.pingdom.com. It also shows a huge delay because of [object%20HTMLDivElement].

For now I commented out this part of code, the problem vanishes, nothing effected as far as I can see.

Please give me some advise with it because its a momentary cure.
