Comment 13 for bug 1038522

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.
