did you try with revision 5a17a43 as advised by Emmanuel?

What happens if you run manually the line "... antebuffer 24 ..." in c130.dup1.stderr.1,
with the final "| gzip -dc -" ? (Maybe redirecting the output to /dev/null.)

Same question by replacing "... antebuffer 24" by "zcat", and removing
the final "| gzip -dc -".

It might be that one of the .gz files is corrupted.

simply with cado-nfs.py ... workdir=...
