avatar – current, upload, crop

followed the install instructions, when i go under the avatar section i don’t see a default avatar. when i go to add one, i get the below error:

Warning: getimagesize(http://domain.com/user/avatar/avatar_adam.gif) [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 404 in /homepages/38/d218960724/htdocs/wp-content/mu-plugins/avatar.php on line 244

when i try to crop the uploaded image, the box to crop doesn’t cooperate.
