This bug also affected me with Ubuntu 14.04 and encrypted home-directory. The swap partition existed but was not mounted as a crypted swap.

My workaround:

Changing /etc/crypttab in (e.g.):

#cryptswap1 UUID=a81fe18e-0f2a-4571-adeb-a80d57015549 /dev/urandom swap,cipher=aes-cbc-essiv:sha256
cryptswap1 /dev/sda6 /dev/urandom swap,cipher=aes-cbc-essiv:sha256

was successfull.
