cryptsetup upgrade from fedora 12 to 13

From Fedora 12 to fedora 13 cryptsetup change default encryption algorithm. I upgrade my workstation OS. And I can't mount encrypted partition. Mount error: incorrect partition type. In fedora 13 You can try next command for example:

# cryptsetup  -c aes-plain  create  crloop /dev/loop7
# instead of:
# cryptsetup  create  crloop  /dev/loop7
# and then mount:
# mount /dev/mapper/crloop /mnt/secret-dir
