Binary package hint: ubiquity

I booted from the newly released Kubuntu 9.04 Desktop amd64 iso and chose the install option.
When asked about partitions, I chose the manual / advanced option.

I have a scsi drive and I already had 2 ntfs partitions (sda1 and sda5) + 20 gb free space at the end.
I made two more partitions in the free space, sda6 as ext4 and sda7 as swap (2gb) and I chose to format the ext4 partition.

After hitting next, the installer worked a bit then told me it can't format the ext4 partition and jumped back to the time zone selection page.

Tried again (partitions sda6 & sda7 were already there this time) and got the same error.
Extract from /var/log/messages:

I managed to complete the installation by manually creating devices /dev/sda6 and /dev/sda7 before hitting next (I checked and I only had /dev/sda /dev/sda1 /dev/sda2 /dev/sda5, sda2 being the logical partition windows makes):
mknod /dev/sda6 b 8 6
mknod /dev/sda7 b 8 7

I am guessing the installer won't automatically create the device files in /dev after creating the partitions, so it can't format them.
