Description of problem:
When attempting to use kickstart to create a system with LVM on top of RAID 1, the installer craps out.

Version-Release number of selected component (if applicable):
anaconda 19.31.79-1

How reproducible:
Every time.

Steps to Reproduce:
Attempt to install from a kickstart with the following configuration:
# Format the partitions, clear mbr first
zerombr 
clearpart --all --initlabel

part raid.00 --size 768 --asprimary --ondrive=vda
part raid.10 --size 768 --asprimary --ondrive=vdb
part raid.01 --size 4096 --asprimary --ondrive=vda
part raid.11 --size 4096 --asprimary --ondrive=vdb
part raid.02 --size 1024 --asprimary --grow --ondrive=vda
part raid.12 --size 1024 --asprimary --grow --ondrive=vdb

raid /boot --fstype ext3 --device raid1-boot --level=RAID1 raid.00 raid.10
raid swap --fstype swap --device raid1-swap --level=RAID1 raid.01 raid.11
raid pv.00 --device raid1-pv --level=RAID1 raid.02 raid.12

volgroup vg0 pv.00

# Create more logical partitions
# CCE-14161-4, CCE-14777-2, CCE-14011-1, CCE-14171-3, CCE-14559-9  (Rows 2 - 6)

logvol / --fstype ext4 --name=root --vgname=vg0 --grow --size=1024
logvol /tmp  --fstype ext4 --name=temp --vgname=vg0 --size=32768 --fsoptions="nodev,noexec,nosuid"
logvol /home --fstype ext4 --name=home --vgname=vg0 --size=65536 --fsoptions="nodev"
logvol /var  --fstype ext4 --name=var  --vgname=vg0 --size=32768 --fsoptions="nodev"
logvol /var/log --fstype ext4 --name=varlog --vgname=vg0 --size=8192 --fsoptions="nodev,noexec,nosuid"
logvol /var/log/audit --fstype ext4 --name=audit --vgname=vg0 --size=4096 --fsoptions="nodev,noexec,nosuid"

Actual results:
Anaconda crashes; installation is halted.

Expected results:
The system should install with the configuration as detailed in the kickstart file.
