At the request of Andrew Thomas, senior member of linuxquestions.org,
I'm adding the information that I gathered when I encountered with KDE
installer bug.  I've posted information in two other forums while
looking for help to get a workaround or fix to the problem.  The
following are links to the forum threads at linuxmint (Aug-26-2012) and
linuxquestions (Sep-2-2012):

- http://www.linuxquestions.org/questions/linux-mint-84/mint-13-kde-64-bit-installer-crashes-4175425285/
- http://forums.linuxmint.com/viewtopic.php?f=46&t=111087

I'm attempting to install Mint 13 KDE 64 bit into a 30GB partition (/dev/sda7).
sda1 = Mint 13 Cinnamon 64bit
sda5 = Mint 13 Mate 64bit
sda6 = Mint 13 XFCE 64bit
sda7 = **was for KDE**
sda8 = /home for all linux installs
sda9 = swap

sda1 is the only primary partition
sda5-9 are logical drives
All partitions are 30GB with the exception of the swap being 8GB (rarely used since I have 8GB of RAM).

Only the KDE install fails (from USB keys and DVDs). Prior Linx Mint,
Ubuntu, and Arch Linux versions installed without a problem.

Distro:  Linux Mint 13 KDE 64 bit
Issue/Bug:  The KDE Installer aborts/crashes to the live DVD desktop if the user performs manual partition setup/selection.  The bug is not limited to the above distro and may affect 32-bit distro editions as well.

I poked around /var/log/installer and found a file named "debug" with the following:

Title:
  manual partitioning in installer crashes

Status in “ubiquity” package in Ubuntu:
  Confirmed

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   /
