Ubiquity crashes copying system to drive

Crashed installing Linux Mint 9 (Isadora)

Ubiquity crash line 524 main(oem_config)
assert os.path.exists(fs_size), missing filesystem.size assertion error

I was attempting to install Linux Mint 9 as the sole OS onto a MSI Wind U100 clone (Advent 4211) system which was dual boot XP and Mint 8, so I was changing the partition table. Three attempts all resulted in this crash.

Old Partitions:
sda1: FAT32 Recovery (approx 2GB)
sda2: NTFS XP (approx 25GB)
sda5: ext4 Linux (approx 8GB)
sda6: FAT32 Spare (approx 8 GB)
sda7: FAT32 Documents (approx 30GB)
sda8: Swap (approx 5GB)

New Partitions:
sda1: ext4 Linux (approx 15GB)
sda6: ext4 Data (approx 60GB)
sda5: Swap (approx 3GB)

I cannot attach /var/log/syslog or /var/log/partman as when I attempted to log on to launchpad immediately after the last crash Firefox also crashed with no errors reported.

I eventually managed to install Mint 9 by installing Mint 8 with the partitions I wanted and then replacing Mint 8 with Mint 9 onto the partition scheme I had already set up.

This is the same as Bug #188976 in Ubuntu. Needs to be fixed!! I am unable to install Linux Mint since I have multiple partitions.
