Bug description:
  Test install of quantal-desktop-amd64 20121014 (ubiquity 2.12.11)

  I allocated a VM an 8G drive and tossed 8G of RAM at it. I selected
  automatic partitioning with LVM and LUKS. The auto partitioner then
  created a root partition of 2.7G which is too small to install onto,
  and bailed out.

  15/10 17:01:31 <xnox> it works fine with 8GB drives here for me....
  unless it created a (8 - 2.7G) ~= 5.3G swap. Aha. So it tried to go
  for 100% * RAM swap, but it had a minimum hard-code at 2.7 for / which
  is no longer enough.

  so it sounds like this minimum needs to be ramped up in line with the
  requirements for a desktop system now.

  Also the error message was inadequate. It starts "Some of the
  partitions you created are too small." which isn't accurate because I
  didn't create the partitions, and then goes on to talk about steps to
  recover. I clicked "Go Back" and then was taken to partman which
  displayed an error "No modifications can be made to the device
  Encrypted volume (vda5_crypt) for the following reasons:

  In use by LVM volume group ubuntu"

  and spun. At which point I was stuffed. :-)
