Comment (by Ad Timmering):

 Looking a bit deeper, I am puzzled by the test setup, that might be hiding
 a different bug:

 * The archive has a file called `no_permissions` that is `0o0` (zero
 permissions) in the archive

 * The current test assumes the file ends up with something similar to
 `0o664`, which means rw-rw-r--, so also read/write for group and other.

 * The reason this works is because `django.utils.archive.BaseArchive` has
 a method called `_copy_permissions` that only reflects permissions **if**
 the file in the archive at least has 0o4 (owner-read, defined in
 `stat.S_IROTH`). Because this file has no permissions (also no user read),
 permissions are not correctly updated to reflect permissions in the
 archive.
