Summary: bz2 RuntimeError when decompressing file

Initial Comment:
The following code:
echo -n Testing123 | bzip2 > test.bz2
python -c "import bz2; lines =
bz2.BZ2File('test.bz2').readlines()"

produces this output:
Traceback (most recent call last):
  File "<string>", line 1, in ?
RuntimeError: wrong sequence of bz2 library commands used

Tested on Python 2.4.1 (debian unstable - April 1
2005), and Python 2.3.5 (debian unstable - May 26 2005)

The looks like correct behavior to me.  The test.bz2 file is
not in a valid bz2 format.  I suspect that you've misread
the BZ2File API which is intended for reading and writing
uncompressed data to and from a file in a bz2 format (where
the data is stored in compressed form).

If this interpretation of the bug report is correct, please
mark as not-a-bug and close.
