not a bug, you're misusing those methods.

visible() and sensitive() are bindings for the corresponding flag 
values of the gtk widget.  only the widget implementation has any 
business *setting* those values, and that usually happens deep within 
the implementation at that.  you can read the values at any time, but 
doing so is not really a good idea.  the flag values represent a cached 
version of the widget's state; the actions that correspond to them are 
driven by separate methods.

the visible flag is toggled deep within the machinery of 
Gtk2::Widget::show() and Gtk2::Widget::hide(), and you should *only* 
use those functions to show or hide a widget..  you can check whether a 
widget is visible with Gtk2::Widget::visible or by reading the 
'visible' property.

the sensitive flag is toggled by Gtk2::Widget::set_sensitive(), and 
should be retrieved by Gtk2::Widget::get_sensitive().  there is also a 
'sensitive' property.
