[mythtvnz] tv_grab_nz-py fails to validate

[Bob .]

Hello.

I'm trying to get program guide data for a freeview dvb-t setup.

I have the latest tv_grab_nz-py grabber from:
http://nice.net.nz/scripts/tv_grab_nz-py

with the following version info:
# Last updated 2010-03-14
VERSION = '0.2.6'

Unfortunately it fails to validate as shown below.  Any advice on what's wrong?

Thanks.
