[Plugin: Google Analytics Popular Posts] Extra

I installed this plugin on the testing version of my blog (antrodesigns.com/ifyoucanread) and it seems to have completely broken my sidebar. Checking the site with Firebug, I discovered that the output has an extra </div> tag at the end of the widget that isn’t there when the plugin is disabled. I looked at the php code, but I can’t find it anywhere.
