Which cryptsetup version?

Basically it means that either kesylot has wrong offset
(or there is bug in cryptsetup itself, I recently added
some offset check code here).

Could you send me (to private mail, not to list) dd of this
broken LUKS header so I can check what's wrong?

(just first 4k of device - without private keyslots area,
e.g. only visible information - you can use this command

dd if=<luks_device> of=<backup_file> bs=4096 count=1

Thanks,
Milan
