The docs [1] say that a callback is a function, so I guess that if it
worked before it was just luck.  You should bring it up on the tkinter
list and see what they have to say about it, though.

I'm a bit confused about why you would want to use a class as a
callback anyway.  It looks like when the button is clicked it
instantiates the class and then throws it away?
