Fixed with commit 448de3966e:

--8<---------------cut here---------------start------------->8---
$ zck_gen_zdict netinst.iso.zck 
Trying 5 different sets of parameters                                          
k=1998                                                                         
d=8
f=20
steps=4

Save dictionary of size 112640 into file netinst.iso.zdict
