Email registration and pathauto

I have a site that is Drupal 4.6 with Pathauto. It sends a confirmation email to users with a line something like this:

After logging in, you may wish to change your password at http:// www.. ...com/user/11/edit

But the pathauto has created a URL alias like this:

http:// www.. ...com/user/username

Is there any way to get the registration email to send the new URL alias instead of a user number?
