Toggle Button Bug

[Ruben Safir <ruben mrbrklyn com>]

It seems to me that the togglebutton toggled() function has a but.  
Documentation
says that when called it will change the state of the object.  I  can't 
varify this behavior.
It calls the toogle signal but doesn't seem to change the state of the 
object.

Example Code Below:

result of package config is as follows:
