Bug#769735: Confirm bug

[Andrew Gallagher <andrewg@andrewg.com>]

I can confirm this bug. I am using the beta2 installer DVD1, and trying
to dual-boot jessie on an existing ubuntu box.

Using manual partitioning, I first resized the ubuntu root partition
from 1tb down to 500gb, then attempted to create an encrypted LVM
partition in the free space. This automatically filled the LVM VG with a
single ext4 partition, but I needed an encrypted swap space also, so
went into "configure lvm", but there were no options there to change
LVs. On exiting that menu, partman attempts to detect disks, but hangs
at 81%. I have reproduced this twice.

Andrew.
