[Plugin: qTranslate slug with widget] v0.5 & WP3.3.2 double slash problem

I follow all scrp suggestions, but doesn’t work!
That’s my code from line 337 of qtranslate-slug-with-widget.php:

// see if cookies are activated
	if(!$q_config['cookie_enabled'] && !$q_config['url_info']['internal_referer'] && $urlinfo['path'] == '' && $lang == $q_config['default_language'] && $q_config['language'] != $q_config['default_language'] && (isset($q_config['hide_default_language'])?$q_config['hide_default_language']:true)) {
		// :( now we have to make unpretty URLs
		$url = preg_replace("#(&|\?)lang=".$match[2]."&?#i","$1",$url);
		if(strpos($url,'?')===false) {
			$url .= '?';
		} else {
			$url .= '&';
		}
		$url .= "lang=".$lang;
	}

	$url = ltrim(str_replace('//', '/', $url),"/");

	// & workaround
	$complete = str_replace('&','&',$home."/".$url);
	return $complete;
}
