Summary: tarfile can't extract some tar archives..

Initial Comment:
Here is a small demo to reproduce the same problem:


-----------------8<-----------------8<-----------------8<-----------------8<---
meren at pardus /home/meren $ wget
ftp://ftp.sleepycat.com/releases/db.1.85.tar.gz
(...)
100%[============>] 270,953       17.13K/s    ETA 00:00

20:21:09 (15.25 KB/s) - `db.1.85.tar.gz' saved [270,953]

meren at pardus /home/meren $ file db.1.85.tar.gz
db.1.85.tar.gz: gzip compressed data, from Unix
meren at pardus /home/meren $ python
>>> tar = tarfile.open("db.1.85.tar.gz", "r:gz")
>>> for tarinfo in tar:
...     print tarinfo.name
...
db.1.85
db.1.85/btree
db.1.85/btree/Makefile.inc
db.1.85/btree/bt_close.c
db.1.85/btree/bt_conv.c
db.1.85/btree/bt_debug.c

db.1.85/btree/btree.h
db.1.85/btree/bt_get.c
db.1.85/btree/bt_open.c
(...) 
>>> for tarinfo in tar:
...     tar.extract(tarinfo)
...
>>>  Ctrl + D
meren at pardus /home/meren $ ls db*
db.1.85
db.1.85.tar.gz
meren at pardus /home/meren $ file db.1.85
db.1.85: empty
meren at pardus /home/meren $ cat db.1.85
meren at pardus /home/meren $ 
----------------->8----------------->8----------------->8----------------->8---

Also this file is extracting with the same result too:
ftp://ftp.linux.org.tr/pub/mirrors/gentoo/distfiles/ncompress-4.2.4.tar.gz

This thing is very rarely happening, but it is
happening. Also, I could extract these archives
properly via the native 'tar' binary..


Thanks in advance,
Ciao.

additionally, the same problem appearing when trying to extract 
these archives with the "ark" (yet another kde tool, just a simple 
front-end for the tar command. interesting, isn't it). 
 
 
Ciao.
