Page Title outputting leading/trailing whitespace within H1
In the page.tpl.php file, the page title bit looks like this:

            &lt;h1 class="title" id="page-title"&gt;
                &lt;?php print $title; ?&gt;
            &lt;/h1&gt;


Simply removing the trailing/leading whitespace (tabs and new lines) from the code, did the trick:

            &lt;h1 class="title" id="page-title"&gt;&lt;?php print $title; ?&gt;&lt;/h1&gt;
