Then stock gtk is broken and you'll need to patch it.

First off, the gtk documentation seems clear to me: gtk.RELIEF_NONE means that the button has no 
relief.  It doesn't say "it'll have a relief when pressed but no relief when not pressed".  It says it has *no* 
relief.

Second, there are hundreds of reasons why you'd want no relief at all, but the humongous obvious one 
is: when you're drawing your own button border or shape!  For example, your logic draws one image 
when pressed, and another when not pressed, and that's precisely what you want your button to look 
like.  This is a very common need, and is supported in every toolkit I can think of.  Except, apparently, 
GTK.

Maemo doesn't have the same needs as stock gtk.  It's operating in a stylus environment where there is 
NO 'hovering' at all!  A hover state is _completely_ nonsensical here.  There should never be a hover 
state on maemo.

And even if it wasn't nonsensical, I need to reiterate that gtk.RELIEF_NONE means "no relief", not "no 
relief, except during hovering".

Last, why is the hover state appearing AFTER a stylus has pressed it?  It makes no sense to the user at 
all.

As it stands, Button cannot be used to make custom buttons under maemo because it is impossible to 
prevent Button from arbitrarily drawing borders due to mistakes in Nokia's styles and broken GTK 
behavior.
