Title:
  ubi-partman crashed with eit code 141

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  This is a fresh install using x86_64 nightly from 20120831 on a new Ivy Bridge laptop with 1TB HD partitioned before the install as

  ==============================================

  I get past the "preparing to install Ubuntu" page but after 5-10 seconds I get a "ubi-partman crashed dailog" with the error "ubi=partman failed with exit code 141"
  The "try again" button gets the same error. I am unable to get further in the installation.

  There are a number of other reports of this for older Ubuntu releases
  but as this was reproduced on the 12.10 nightly I thought it deserved
  a new bug. It is 100% reproducible

  I am a developer and happy to try patches or collect more debug info.

  
  My basic analysis:
   * ubi-partman failing with 141 is SIGPIPE
   * The python traceback in /var/log/syslog suggests /var/lib/partman/outfifo (FIFO to parted_server) could not be opened. outfile is a zero length file afterwards, but does seem to be a FIFO as the installer is running. I tried a time.sleep(1) before outfile was opened but it did not help.
   * The parted_server log in /var/log/partman suggests that parted_server did service requests via the FIFOs and was then asked to QUIT (but that might be a reaction to an earlier failure).
