Couldn't commit to pristine-tar - This doesn't look like a tar archive (continued)

Hi,

I've been stuck with this since months and no clue how to get around,
so any insight would be welcome: when I call gbp import-orig --uscan, a
tarball is downloaded, but can't be committed to git, because of the
error in the title.

After some poking around, I know:

- the downloaded tarball is correct ;

- checking out the git tree anew doesn't solve anything ;

- pristine-tar is as far as I know the culprit ;

- creating a new account on the same box gives the same problem, so
it's not a configuration issue.
