Bug description:
  Binary package hint: debian-installer

  I was running Ubuntu 8.10 32-bit, with an encrypted partition and LVM.
  I went to install Ubuntu 9.04 64-bit, hoping to reuse the same LVM
  volumes, just replacing the volume for /, leaving /home and so on
  intact.

  I fired up the 9.04 installer, got to partitioning. I chose manual,
  saw my two partitions listed, both marked "do not use". I activated
  the second partition and chose "physical volume for encryption". Now
  to see the data, I selected "Configure encrypted volumes". At this
  point a message appears asking me if I'm happy with the partitions, I
  choose yes, I'm asked for an encryption passphrase, I enter it, twice.
  At this point, I'm suspicious, I reboot to my existing 8.04
  installation. My encrypted partition has been completely destroyed,
  there is no LVM available and no data.

  The text in the installer should make it absolutely clear that when
  you choose yes at the "Configure encrypted volumes" option, this will
  destroy any encrypted data on the partition.

  Thankfully I had sufficient backups. What seemed like a routine
  install actually destroyed all my data. :-(
