I'm using Xubuntu 14.04 LTS, installed via minimal install CD and booted from hard drive, not USB. I tried the workaround mentioned here https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1301383/comments/6 , one try adding offset=8 to the script, another replacing the UUID reference with my swap partition, /dev/sda5 (not both at once), and neither worked (even on first reboot), still get the message on startup. Both attempts had in common that fdisk -l showed this:
Disk /dev/mapper/cryptswap1 doesn't contain a valid partition table

Both attempts had in common that fdisk -l showed this:

and swapon -a showed this:
swapon: /dev/mapper/ cryptswap1: read swap header failed: Invalid argument
Reverting to unencrypted swap worked.
