I am using 9.04 and had this exact problem appear sometime in the past 2 weeks (not 100% sure when). I was able to use mount.crypt (thanks jhansonxi) to mount the drive. cryptsetup fails 100% of the time with 10 different hard drives. I think it goes without saying that for those of us who make use of luks encryption, not being able to access a hard drive is a really serious problem. Attached is an strace I made during a failed mount attempt.
