[Bug 1169611] Re: 13.04 installation has damaged my luks partition

Here's a fdisk output.
The configuration is the same as before Raring.
On sda5, there's a LVM partition which can be analysed on the first attachments of this bug (vgdisplay and lvdisplay).
The only difference is that I didn't have /dev/ubuntu/raring. The /dev/ubuntu/root partition had 30GB and I decreased it's size to create raring. The /dev/ubuntu/root partition has 12.10 still working. 

Thanks for taking time to work on this.

Title:
  13.04 installation has damaged my luks partition

Status in “ubiquity” package in Ubuntu:

Bug description:
  Some days ago I've installed ubuntu 13.04 beta2 release on a clean
  partition I had.

  I've chosen in the installer to not touch my home partition as it's
  encrypted and I doubted it would not understand that.

  I chose the root partition and asked to encrypt my swap partition.

  After installation I couldn't open my home partition any more. It keep
  saying:

    hugo at scare:~$ sudo cryptsetup luksOpen /dev/ubuntu/home home_crypt
  Device /dev/ubuntu/home is not a valid LUKS device.

  I don't know what the installer thought about my partition but I expected it to not touch that.
  I am still trying to not go crazy about it but I didn't have the luks partition header on my backups and I have almost zero hope on recovering that. I just expect it to be fixed in a near future.

  It seems  ubuntu installer still has little support for lvm+luks
  partitions on installer.
