[Bug 1038522] Re: [kde] manual partitioning in installer crashes

[Dmitrijs Ledkovs]

@Ghoulish:
The developers did not manage to reproduce this bug on neither Ubuntu 12.10 nor Ubuntu 12.04.
We believe the bug is not present in Ubuntu 12.10 as there are currently no reports that this bug is present in 12.10 -> hence I mark quantal task incomplete.
Precise task is still open and confirmed on the grounds of multiple reports of affected users.
But again, there are no reliable minimal steps to reproduce this bug, therefore developers cannot start fixing it.
If you can create a list of steps (preferably in a VM) that need to be done to trigger this bug with _official images_, it will be amazing.

Please note, just because something is based on *buntu 12.04 it does not
make it long term support. Kubuntu & Ubuntu 12.04 official repository
and official images are supported. See release manifest and support
designation statuses over here:

Bug description:
  when choosing manual partitioning, installer crashes when setting mount points. after many attempts where the installer just disapeared, I got:
  Exception in KDE frontend (invoking crash handler):
  Traceback (most recent call last):
    File "/usr/lib/ubiquity/ubiquity/frontend/kde_components/PartitionModel.py", line 105, in parent

  rather frustrating - I can set up 2 or 3 partitions before it crashes. I have 2 disks, sda and sdb and it doesn't reliably crash on any particular partition or disk. My Machine is currently a dual-boot Kubuntu 10.04 / Win 7 Ultimate. I wanted a complete fresh start for 12.04 so I was going to format the linux partitions

  sda1 bootable, NTFS
  sda2  Extended
  sda5  ext4  /home
  sda6 ext4  /var

  sdb1 NTFS
  sdb2 bootable ext4 /boot
  sdb3 Extended
  sdb5 ext4   /
