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

[Andrew Heil]

To be more specific about my situation: I have a 1.5 TB hard drive with
16 partitions (one of which is an extended partition containing other
partitions). The partitions are a mix of formats: ntfs, fat32, ext3, and
ext4. (I like to play with different distros. Most people are obviously
not going to have this scenario. Kubuntu is installed on sda1, and its
GRUB is "in control", if you will.)

As I mentioned earlier, this crash has never occurred while installing
Ubuntu; it's just occurred while using the KDE/QT flavor of the
installer.

I downloaded Kubuntu 12.04.1 and tried the installer (Ubiquity v2.10.20)
yesterday. I chose manual partitioning, and started adding partitions at
random (using one as / and mounting the others in /mnt). This time, the
installer didn't crash until I added the 9th partition, so it was more
robust than before.

The last lines of /var/log/installer/debug were:
QSocketNotifier: Invalid socket 17 and type 'Read', disabling...
QSocketNotifier: Invalid socket 17 and type 'Exception', disabling...
QSocketNotifier: Invalid socket 17 and type 'Write', disabling...
KCrash: Application '' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit

I tried to duplicate this in a virtual machine a couple of times,
finally creating a fixed size 25GB hard disk in VirtualBox 2.0 and
creating 7 partitions (one of them swap, one of them extended) with
gparted before running Ubiquity. It crashed some times and not others.
In other words, it didn't consistently occur.

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   /
