In Python 2.5.1's tarfile.py, we have:

def __init__(self, name=None, mode="r", fileobj=None):
        self.name = os.path.abspath(name)

If name is None (e.g. extracting from a stream) we get e.g.:

Traceback (most recent call last):
  File "tarfile.py", line 1168, in open
    _Stream(name, filemode, comptype, fileobj, bufsize))
  File "tarfile.py", line 1047, in __init__
    self.name = os.path.abspath(name)
  File "posixpath.py", line 402, in abspath
    if not isabs(path):
  File "posixpath.py", line 49, in isabs
    return s.startswith('/')
AttributeError: 'NoneType' object has no attribute 'startswith'

It works with Python 2.3.6, 2.4.4 and 2.5.0, but not 2.5.1.

(discovered by Zero Install unit-tests)

Thanks,

Apparently this is a duplicate of #1695229. It was fixed in rev. 54889 in release25-maint, about a week too late for 2.5.1 :-(
I attached a patch with the changes.
