New submission from Sridhar Ratnakumar <sridh...@activestate.com>:
Much like zipfile.BadZipfile, we need a base custom exception for the
gzip module. At least, catch gzip-related exceptions and throw a
tarfile.TarError when used *via* tarfile.*.
See the following example (the exception escaped the "try... except
tarfile.TarError: .. " block!):
