I think I found the fix:

Installer was freezing during installation ( ubuntu-gnome 15.04 USB ).

I jumped over to a tty and checked the process list: $ ps -ef --forest

The process that was stalled was: mkfs.ext4 /dev/sde1

I kill -HUP it's pid, and then ran the command by hand: and I get a prompt:

$ sudo mkfs.ext4 /dev/sde1
mke2fs 1.42.12 (29-Aug-2014)
/dev/sde1 contains a ext4 file system
        last mounted on / on Wed May 6 06:10:18 2015
Proceed anyway? (y,n)

Looks like ext4 added a check that will need to disabled with a -F (?? is that safe ??) OR have an expect script handle the prompt.

tl;dr mke2fs is prompting to confirm if existing ext4 partition detected. Prompt is not handled, causing install to hang.
