I can confirm this bug. I have my root fs on LVM on a LUKS encrypted md1. Same version of Ubuntu and Cryptsetup as razboinik.
The mounting usually succeeds after entering the password three or four times. The first time it always fails because "/sbin/cryptsetup isLuks" fails to detect that it's LUKS. The second and third failure are usually due to unknown fstype.
If I wait some time before entering the password the second time, it succeeds.
