Update of /cvsroot/python/python/dist/src/Lib
In directory sc8-pr-cvs1:/tmp/cvs-serv25917

Modified Files:
	gzip.py 
Log Message:
[Patch #654421 from Matthew Mueller] 
  gzip shouldn't raise ValueError on corrupt files

  Currently the gzip module will raise a ValueError if the file was
  corrupt (bad crc or bad size).  I can't see how that applies to
  reading a corrupt file.  IOError seems better, and it's what code
  will likely be looking for.
