Can you report it upstream please? http://code.google.com/p/cryptsetup/issues/list
(With some reproducer please. You need space for keyslots on LUKS header device,
not on data backing device, so I still do not see what problem exactly you see here,
header file must have a least space for header + all kesylots.)
