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:2507: in next

```
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.
