Hi
I cloned the git repo from nibabel and did some tests. I saw the HEAD of
upstream doesn't have this problem. The difference from the HEAD to the 2.1.0
version in the file with the error is diff I've attached in this email.
Applying this diff fix this problem. I think you can send this patch to the guy
which packages nibabel.
Kind regards.
