Bug in module gzip

[Konrad Hinsen]

In past Python versions I have had various problems with the gzip
module, but several told me that they were fixed in 1.5.2. So I looked
at it again, only to get an immediate crash when reading a gziped file:

  File "/usr/lib/python1.5/gzip.py", line 270, in readline
    c = self.read(readsize)
  File "/usr/lib/python1.5/gzip.py", line 157, in read
    self._read(readsize)
  File "/usr/lib/python1.5/gzip.py", line 210, in _read
    if self.decompress.unused_data != "":
AttributeError: unused_data

The attribute unused_data is in fact never set. It should thus be
impossible to read any file at all, which makes me wonder if nobody
noticed this before... and perhaps has a fix!
