I had the same issue today, while trying to install testing. But my case
is slightly more confusing since I did *not* have any swap partition shown
in /proc/swaps (I restarted the install from scratch and checked in the
alt+F2 console before and after launching the partition manager).
As mentionned in bug #396138 (merged with this one), the only way has been
to set my swap partition to "Use as: Do not use" in the partitioner.
Automatic partitionning yielded the same result, and my disk was a new,
unpartitionned SSD.
I do not understand what is going on. I already used the automatic
(and even manual) partman-crypt in the past and never faced such an issue.

I'm afraid I do not understand: I have installed several Debian systems in
the past featuring an encrypted swap partition. The fact that it
(sometimes) does not work looks like a random bug, not an absolute
impossibility.

Then again, swapoff did not solve the issue in my case. Somehow, the
installer seems to think that, because I want to configure a swap
partition, a swap partition is already setup and might leak my passphrase
(which is not the case, and anyway this is supposed to be an encrypted swap
so WTF?).
