indeed ;) me is also swamped with work, so no diving into combinatorics
or recursive code comprehensions.
Hence, for now, we provided a fix which should work for cvtype>2 BUT for
a sane number of unique chunks (ie < 20). Otherwise it would fail at
number of unique chunk ids > 20 I guess... didn't check carefully yet ;)
But otherwise it works fine now. Fix is present in yoh/master and
maint/0.4 branches.
enjoy -- and thanks again for spotting and reporting evil things ;)
