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

[Petr Sigut]

Hello,

I am writing plasmoid in ruby and I need to remove widgets on the fly, I was 
pointed to dispose method, but if I use it, the plasmoid crash, when I try 
dispose QT button, everything works. 


# disposing QT button is ok
      qt_button = Qt::PushButton.new('Hello World!')

      # prints object
      puts qt_button

      # prints nil
      puts qt_button.dispose

# disposing Plasma button is crash
      plasma_button = Plasma::PushButton.new

      # prints object
      puts plasma_button

      # crash
      plasma_button.dispose

Zipped plasmoid, just plasmapkg -i test-widget.zip and
plasmoidviewer test-widget
http://tmp2.sigut.net/test-widget.zip

I appreciate any help, I tried several different methods (removeAt, ...) but 
with no luck. I will also provide any other information needed.

I use Ubuntu 9.10 beta, KDE 4.3.2
