Profile in Joomla 1.5 custom module not redirecting properly

Hi, I posted this in the forum and it was recommended I file an issue. Original post is here:

Issue is: We're using the standalone code for a profile which we've inserted into a Joomla 1.5 mod_custom module (to use as a email signup), but when you submit the form it redirects to the Joomla Admin instead of the redirect we specified in the profile. This happens even if I set the redirect to be something like google.com. We're running CiviCRM v 2.1 beta4. The URL it tries to redirect to is:

http://<site root>/administrator/index2.php?option=com_civicrm&task=civicrm/profile/edit&gid=1&reset=1&
