Title:
  Ubuntu 12.04.1 crash in installer on VirtualBox

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  I was installing ubuntu 12.04.1 (32 bit version time time, but I had
  the same problem with the 64 bit version) on a virtual machine in
  Oracle's VirtualBox (version 4.2.6).

  My VM's specs:
  1024 MB RAM
  12 MB video memory
  32 GB Hard drive

  I downloaded the image from www.ubuntu.com/download/desktop the image
  name was ubuntu-12.04.1-desktop-i386.iso it was 695.29MB in size.

  I picked: install, selected to pick updates while installing. Did NOT
  pick to install third-party software.

  It was confirmed that yes, I have at least 4.4GB of drive space, yes I
  was connected to the internet, yes I was connected to a power source.

  I picked to Erase disk and install.

  I installed on /dev/sda which is a ext4 file system.

  I picked the new york time zone and English keyboard layout.

  Installer reports:

  "Installer crashed. We're sorry; the installer crashed. After you
  close this window we'll allow you to file a bug report using the
  integrated bug reporting tool."

  Last thing it says it's doing:

  "Removing extra packages..."

  Details:
