problem with GKT module?

[alister ware]

I am using gtk.builder with a glade generated GUI

I have a simple call back defined for a radio button widget when I use 
widget.name in linux I get a value of None, windows returns the widget 
name as I would expect.

is this a bug?
if not how should i find the name of the widget that has triggered a call 
back?

(I would like all my radio buttons to go to the same callback routine if 
possible to make code maintenance easier)
