See #917789 - that's what you are seeing.
gbp import-orig does extra things (that honestly I don't understand why
they are needed), and plain pristine-tar can't checkout a tarball, as
the tree id recorded are something that is build especially by gbp.  You
need to use `gbp export-orig` to export such tarballs.

If you wish to use `pristine-tar checkout` see #917789 that contains a
way to hack the .id files so that pristine-tar can do its work again
directly, without the help from gbp.
