Title:
  Server installer crashed when trying to partition 4k/4k sector hard
  disks

Status in “partman-base” package in Ubuntu:
  Confirmed

Bug description:
  partman_server crashes on Ubuntu 12.10 server for amd64 when trying to
  partition an Advanced Format (4k / 4k sector) hard disk.

  Disks that utilize 4k sectors with 512 emulation work fine.  The
  installer has no problems with those.

  Steps to Reproduce:
  1) Begin the installation in EFI mode. 
  2) At the disk partitioning stage, select "Guided use Entire Disk" or "Manual"
  3) Review and accept the proposed partitioning scheme and write changes to disk. 

  Actual Results:
  The system will attempt to create a the EFIboot partition.  At this stage the installer appears to hang.   Pressing Ctrl+AltF4 reveals that parted_server has crashed with the following message:

  parted_server[13865]: segfault at 22fa000 ip 00007fa6eb74bee7 sp
  00007fffec3ab500 error 4 in libparted.so.0.0.1[7fa6eb735000+64000]

  Expected results:
  Installation should carry on without a crash.
