BUG - SquidGuard Redirects No Longer Working in 1.8

Greetings,

After upgrading from 1.7 to 1.8, my SquidGuard redirects are no longer working properly, but my users get redirected to a page that says a URL error occurred and "Access denied."  This is with the exact same configs.  I understand that SquidGuard has been uprgaded in 1.8, so perhaps something's broken somewhere.  My config is as follows:

# show service webproxy
 cache-size 200
 default-port 3128
 enable-access-log
 listen-address 192.168.150.1 {
 }
 mem-cache-size 5
 url-filtering {
     squidguard {
         default-action block
         local-ok intranet.application.net
         local-ok  intranet.application2.net
         local-ok webmail.application.org
        ...
         redirect-url http://intranet.application.net:8090/
     }
 }

Rolling back to 1.7 fixes the issue.
