register links with destination= fail to forward to the role register page

On a site I have I can consistently reproduce this behavior. When I have rolesignup enabled links in the form:

http://www.example.com/user/register?destination=node/5%2523comment_form

Will redirect to node/5%2523comment_form instead of user/register/role. Ideally they should redirect to user/register/role, preserve the destination, and pass the destination on to the user/register screen. I'm using rolesignup from about two weeks ago (it would be beneficial to add a // $Id$ to the top of the file so we know which version it is).
