Not doing a very deep analysis.  I think the problem here is the way
gtk handles signals, return values and default handlers.  Basically it breaks
the save signal.

We might have to change that framework to be slightly different.  Basically
AFAIK right now, "first" type signals don't work right with return values,
and for "last" type signals, the default handler overrides the return value.
So my proposed solution (I won't do it right now, but it's a simple change)
Is to bind the "save" signal with gtk_object_connect_after, and make the
signal a normal last type signal.  That should make it all work.
