Sorry for the delay Peter,

many bugs arround.

In moment the ubiquity(the installer) is in versionn 2.11.30 available:

http://cdimage.ubuntu.com/daily-live/current/

Your report depends on ubiquity 2.10.16, so there is a big gab.

This is not necessary, but nlwould be helpfull when you can do a retest
for us.

Thank you for your report

When the problem is fixed please set the status of the report to Fix
Released, when not leave a message here and let it on confirmed.

Title:
  migration-assistant unable to unmount target
  -"/usr/lib/ubiquity/ubiquity/install_misc.py", line 260, in start

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  While installing Quantal 12.10 on my iMac, overwriting Precise 12.04 on partition sda7, I got migration-assistant telling me that it couldn't unmount sda7. Using a terminal I saw that sda7 was mounted on /target, presumably used by the installer.
  I could have unmounted manually, but I decided to continue installing despite possibly losing existing files on 12.04.
