Title:
  Precise Desktop 64Bit: libc6 fails to install if "install 3rd party
  software" is selected

Status in “ubiquity” package in Ubuntu:
  In Progress
Status in “ubiquity” source package in Precise:
  In Progress

Bug description:
  Trying to install the Precise Alpha1 release candidate (64-bit) on
  VirtualBox on a 32-bit Ubuntu guest, ubiquity crashed while installing
  the system and asked me to file a bug.

  TEST CASE
  1. Use Precise Desktop AMD64 and start the installation
  2. In step 'Prepare' select 'Download Updates while installing' and 'Install third party software'
  3. Proceed with the installation

  EXPECTED RESULT:
  The system installs

  ACTUAL RESULT:
  The installation fails and the following error is displayed in the logs:
