[Kde-bindings] qtruby: Qt::String uninit const

[jm]

I have the following in a class

class Thing < Qt::Widget
   ....
def  paintEvent(e)
     #s = Qt::String.new('aweeee') #Time.now.strftime('%H:%M'))
     p = Qt::Painter.new(self)
     0.upto(5) do |n|
       p.drawText(50,50*n, ".")
     end
     s =   Qt::String.new(Time.now.strftime('%H:%M'))   #<--- line 45
     p.drawText(250, 20, 50, 25, Qt::AlignRight, s)
     p.drawLine(20, 50, 280, 50)
     p.end
   end
....
end

It doesn't seem to matter where I put Qt::String it gives me some thing 
like

main.rb:45:in `const_missing': uninitialized constant Qt::String 
(NameError)
         from main.rb:45:in `paintEvent'
         from main.rb:90:in `method_missing'
         from main.rb:90

Most likely an obvious error I just can't see at the moment. Any 
suggestions?
