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

[Ghoulish Teknology]

@Dmitrijs:

I did not encounter the problem in VirtualBox because I used the basic partition strategy where it uses the entire virtual hard disk (VHD).  To attempt to reproduce the problem in a VM, one would have to do the following:
- create a new VM with a large virtual hard disk (140 GB is big enough)
- give the VM 2GB or 4GB RAM
- Use Ubuntu 12.04 64bit as your first install.
- During the Ubuntu 12.04 64bit install, partition the VHD to match my partition scheme
 <quote>
sda1 = Mint 13 Cinnamon 64bit  <--------  INSTALL UBUNTU 12.04 64BIT HERE
sda5 = Mint 13 Mate 64bit
sda6 = Mint 13 XFCE 64bit
sda7 =  <----------------  INSTALL K-UBUNTU 12.04 64BIT HERE
sda8 = /home for all linux installs
sda9 = swap
</quote>

- The listed partitions above should be 25GB, with the exception of sda9
(swap).  SDA9 should be 8GB.  What you won't see listed in my quote
above is the large extended partition (might be sda2).  The large
exentded partition should be 108GB.  SDA partitions 5 to 9 must be
logical drives within the large extended partition.  There will be left
over unpartitioned space.  This is exactly the non-standard partition
setup you want to test against.

- Do the installs in order by the partition, but keep in mind that you need to create a unique user ID for each OS install since the user folders will reside on the same user home partition.  For example, I used the following user ID naming scheme:
gh-ubuntu120464 (ubuntu 12.04 64bit)
gh-lm1364cinnamon (mint 13 cinnamon 64bit)
gh-lm1364mate (mint 13 mate 64bit)
gh-lm1364xfce  (mint 13 xfce 64bit)
gh-kubuntu120464 (k-ubuntu 12.04 64bit)

You will have to choose the manual partition option for each install.
During the K-ubuntu 12.04 64bit install, pick the manual partition
option, and be sure to select the swap partition and mark it as swap (it
will already be a swap partition, but do it anyway).  Somewhere during
the manual partition selection process you should encounter the
installer failure with or without error messages.  If there are no error
messages after a failure look in " /var/log/installer" for a file named
"debug".  Use the links in my posts toward to the top if you need error
message info to compare against.

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):

  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   /
