Installer crashed while creating encrypted volumes on two drives

[Ron HD]

Trying to install Kubuntu on a ssd on /dev/sdb and hard drive on /dev/sda, with boot loader and boot partition on the ssd. The rest of the ssd space is to be encrypted, and all of the hard drive. Trying to create the second encrypted volume seemed to trigger the error.
