This is not fixed if both of the swap partitions are encrypted. I am not sure if this is the same bug or different bug (e.g. https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/571682). My root partition is on 2 disks using RAID 1 using mdraid and is encrypted using LUKS. Each of these disks contains also swap partition which is encrypted but not configured using mdraid since kernel doesn't need it.

In my /etc/fstab I have
/dev/mapper/ sda2_crypt none swap sw 0 0 sdb2_crypt none swap sw 0 0
/dev/mapper/
In my /etc/crypttab I have
/dev/mapper/ sda2_crypt none swap sw 0 0 sdb2_crypt none swap sw 0 0
/dev/mapper/
Only of these partitions is mounted upon start. The other one is not mounted nor decrypted.
