notice you’ve added the fix ( a more proper one i might add ).
another thing though…
on line 946 (v2.3), I also add the title parameter to fbshare
$dd_fbshare_iframe = "<script type=\"text/javascript\"> var fbShare = {url: '" . $digglink[0] . "',size:'" . $dd_fbshare_design . "', title: '".get_bloginfo('name').' - '.$title."'}</script>";
