Grub Error durring kickstarts.

I started testing Hardy's ability to kickstart during beta with zero issues. When Hardy went production something changed and now I am getting GRUB errors when it comes time to install the bootloader. The kickstart that was finishing un-attended during beta now drops to the install menu. To continue and finish the kickstart you have to pick the 'continue with out boot loader' option. Once the system restarts GRUB starts and the system functions properly. Attached is an image of the error that occurs. Looking through syslog I have also found an error message that is produced by GRUB when the kickstart is halted. This error is: 'error: Preseeding of encrypted passwords changed! Check installation guide.' The line we use in kickstart to install the boot loader is 'bootloader --location=mbr --md5pass=$1$zGQvkuRk$mkX73Zt4GuT4V8cyqPQS10' (this is the hash for "password" and is not our actual hash). This line has not changed since Hardy beta. No where have I been able to find documentation on how the syntax has changed. The gui 'Kickstart Configurator' that is installed from package system-config-kickstart even generates this line exactly the same. I also verified that our grub password is not being installed.
