Are you sure that cryptsetup is installed on your stick/cd/nfs 
installer? The log output does not have any

Maybe you could also try to use the "Plain disk + LUKS + LVM2" example 
directly (i.e., with a legacy PC bootloader, maybe even in a VM). I 
think I once had this running in the past for testing.

For debugging setup-storage related issues I found it useful to add the 
"-d" option. After an installation has failed, you can just run 
setup-storage manually from the command line or via SSH and check the 
contents of its internal lists of the actual and desired config.
