New submission from Tomas Tomecek:
I have a tarball (generated by docker-1.10 via `docker export`) and am trying
to extract it with python 2.7 tarfile:
```
with tarfile.open(name=tarball_path) as tar_fd:
tar_fd.extractall(path=path)
```
Output from a pytest run:
```
/usr/lib64/python2.7/tarfile.py:2072: in extractall
for tarinfo in members:
/usr/lib64/python2.7/tarfile.py:2507: in next
tarinfo = self.tarfile.next()
/usr/lib64/python2.7/tarfile.py:2355: in next
tarinfo = self.tarinfo.fromtarfile(self)
/usr/lib64/python2.7/tarfile.py:1254: in fromtarfile
return obj._proc_member(tarfile)

errors = 'strict'
def decode(input, errors='strict'):
> return codecs.utf_8_decode(input, errors, True)
E UnicodeDecodeError: 'utf8' codec can't decode byte 0xc0 in position 4:
invalid start byte
/usr/lib64/python2.7/encodings/utf_8.py:16: UnicodeDecodeError
```
Since I know nothing about tars, I have no idea if this is a bug or there is a
proper solution/workaround.
When using GNU tar, I'm able to to list and extract the tarball.
