kubuntu lucid crashes during manual partition

[Peter]

Binary package hint: base-installer

Installing Kubuntu 10.04 Lucid AMD64 from live CD.
During manual partition (allocating mount points to existing partitions), the installer crashes. It just vanishes and drops back to clear desktop of the live CD.

The error check from the CD boot menu reports no errors.

Running the installer from the CD boot menu (instead of running the live CD first) gives similar symptoms. At the same point in manual partitioning, the installer crashes to a black screen, then starts a live CD session of KDE.

This hardware installed the beta version of Kubuntu Lucid 10.04 AMD64 without error, and has run earlier versions of Kubuntu without this problem.

For me the installer crashed when I created and extra partition (ext4) with a non default moint point /scratch

I use i386 32bits version, happened to me too: attaching partitions (ext3 and fat32) on non-default location. After returning to live desktop I tried again and succeeded. I chose btw to remain on the safe side and created only mount points from one physical hard disk.
mount points:
/dev/sda5 /windows ntfs
/dev/sda6 /winlinux fat32 (non-standard mount point)
/dev/sda7 / ext4
/dev/sda9 /home /ext4
(/dev/sda10 swap)

On the failed attempt I also tried to create mount points
/dev/sdb2 /backupext3 ext3
/dev/sdb3 /backupfat32 fat32

I cannot determine on which mount point the installer crashed.
