cryptoloop option is not important, the first one is enough.

What is your kernel version and arch?
(I should add this to cryptsetup debug output :)

1) try it in two steps:

losetup /dev/loop0 crypto.img
cryptsetup luksOpen /dev/loop0 crypto

Does it work this way?

2) try last stable cryptsetup 1.6.1, does it help?

If it still doesn't work, please use cryptsetup 1.6.1
and send (me or to the list) output of:

uname -a
dmsetup table
strace cryptsetup luksOpen crypto.img crypto --debug
