[BangPypers] ReadError: opening tar file

[murugadoss]

Thank for the reply.
The tar file is not corrupted, i am using the same file in 32-bit m/c and
able to extract it. I have attached this output also with the mail.
I am getting this problem only in 64-bit m/c.

output from 32-bit m/c:
tarfile.is_tarfile(tar)
func <bound method type.gzopen of <class 'tarfile.TarFile'>>
func1 <tarfile.TarFile object at 0xb7f028ac>
True

For reference i have tested the same in different systems.

Thanks & Regards
