Tags being added that are unwanted

Hi, ckeditor is great but im having problems with it, im using it on a bespoke CMS i have written, when you create a page and enter text into ckeditor it is fine, but when you view the page you created there is an annoying

<p>&nbsp;</p>

added to the start of the output, if i remove it manually it goes but ckeditor seems to be adding it in by itself, i have trawled this forum and the net and cannot find anything to help, i did find the following code on another site to maybe try and i have but didnt solve the problem:

    CKEDITOR.on('instanceReady', function(ev)
    {
        var tags = ['p', 'ol', 'ul', 'li', 'h1', 'h2', 'h3', 'h4'];

        for (var key in tags) {
            ev.editor.dataProcessor.writer.setRules(tags[key],
                {
                    indent : false,
                    breakBeforeOpen : false,
                    breakAfterOpen : false,
                    breakBeforeClose : false,
                    breakAfterClose : true
                });
        }
    });

Can someone help me please? Thanks in anticipation.
