Oops. If you look at all the examples of menu-radio-group and/or 
meditate on the prefix "menu-", you will see that that bad boy belongs 
only in menus (where packing does not apply).

Were you just trying to make an always-visible radio group? Was there an 
example in lotsa-widgets? A quick scan of the hierarchy suggests you 
just want a subclass of frame-selector, either frame-stack or frame-row. 
Either one will give radio buttons a parent selector that will 
effectively manage them. If I am lucky. :) If not I'll dig deeper.
