Redirect path in login URL is bad

With the Multisite Privacy plugin activated, the URL that I am redirected to after logging in is invalid. For example, if the site "" is made private, the URL that I am forwarded to when I try to access the site is "" (notice how the "/wordpress/mysite/" portion is duplicated).

After logging in, I am directed to the page (again, the "/wordpress/mysite" is duplicated) which is "Not Found" due to the incorrect path.
