Thanks for the example.
I played a bit more with Glade and I found that if the action is described
as a detailed action, i.e. "win.radio-action(0)", then the application acts
as if I haven't define such an action. It appears as if the buildable is
using the entire string as the action name and fails to parse the action
name vs. the action target.
If I remove the detailed portion. i.e. "win.radio-action", the the action
is "connected" but now complains that the parameter does not match.
If I remove the target from the action and just connect the "change-state"
signal without connecting the "activate" signal, the "change-state" signal
handler does not get called at all.
It just seems like there is something broken with Glade's or libglade's
handling of the detailed action.
