The data type for bytes in Python 3 differs from the one in Python 2. The type cast that is compatible with both versions was applied. Signed-off-by: Andrey Shinkevich <andrey.shinkevich@virtuozzo.com> Reported-by: Kevin Wolf <kwolf@redhat.com> --- v2: The TypeError in Python3 was handled based on the version check.
