[Kde-bindings] ruby - dispose QT button OK, plasma button crash

[Petr Sigut]

I found solution

     while ((@child = @layout.itemAt(0)) != nil)
        @layout.removeItem(@child)
        @child.dispose
      end

plasma_button get by @layout.itemAt(0) is that type: 
<Qt::GraphicsLayoutItem:0xace878c4> and could be dispose() flawlessly.

if I "puts plasma_button" it is that type: <Plasma::Label:0xace89cdc> and 
dispose() crash...

but still I do not know why:)
