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

[Ghoulish Teknology]

@Rick Graves:

Thanks for your suggested work around, but it doesn't work with
LinuxMint 13 KDE 64bit.  I haven't tried installing Kubuntu 12.04.

During the Mint 13 KDE 64bit Install I do *not* create partitions as all partitions were already created from within Mint 13 Cinnamon 64bit.  Grub was already installed during the Cinnamon 64 bit install.  So, during the KDE install I pick the manual partition option to select the partitions for /root, /home, and swap.  During the first install attempt I did not have the KDE installer reformat the sda7 partition as it was formatted from within the Cinnamon 64 bit install.  During another install attempt I let the KDE installer reformat the sda7 partition.  The KDE installer crashed during both attempts, and went on to crash in all remaining attempts.  So after the first two failed install attempts I tried the following:
- reboot, run the install, let the install crash, and then just re-run the install again without rebooting
The install continues to crash.

All of the other Mint 13 disto installs completed without any problems.
Prior to the Mint 13 installs several other Linux distro versions were
installed without a problem.  During the Mint 13 Cinnamon 64bit install
I removed all of the prior partitions and recreated the partition setup
listed in my first post.

Bug description:
  when choosing manual partitioning, installer crashes when setting mount points. after many attempts where the installer just disapeared, I got:

  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   /
