the title matches
https://errors.ubuntu.com/bucket/?id=/usr/lib/ubiquity/bin/ubiquity:ValueError:watch_debconf_fd_helper:process_input:wait:cleanup:preseed:%3Clambda%3E:command
which is one of the most reported precise issue

Title:
  ubiquity crashed with ValueError in command(): I/O operation on closed
  file

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  I tried to install ubuntu with the live daily build of 21/04/2012,
  choosing how to partition the system manually. I own to my hard drive
  with 2 partitions windows 7 and Ubuntu 11.10 x86_64 .. this last has 4
  partitions: / (ext4 journaling), / boot (ext2, without journaling), /
  home (ext4 journaling) and swap .. not touching anything, I just
  canceled the installation and the window partition crashed! and top
  right is another pop icon keyboard!
