Widget for avatars with subdirectorys not working!


I am a new member and have installed the new avatars, now my problem is this:

When using the widget for showing avatar there is wrong urls,
In documentation you create wp-content/avatars/blog and wp-content/avatars/user
in the widget file the url is :<img src="http://<?php echo $current_site->domain . $current_site->path; ?>/avatar/blog-<?php echo $wpdb->blogid; ?>-128.png?ver=<?php echo md5(rand()); ?>"/>
You get one extra / and the directory is avatars not avatar, am i correct?? For me it doesnt work when changing this.
Please help me with this....or am i doing something wrong??
