It looks like things go wonky when Page Navigation is off. There is some CSS with the page navigation that helps define the div above the breadcrumbs and when it's off, the breadcrumbs don't respect that space. So, add to additional.css:

#breadcrumb_two {    
clear: both;    
display: block;    
float: left;    
margin-top: 30px;}
