Summary: TreeCtrl#expand_all crashes (Windows)

Initial Comment:
When running the following code :

require "wx"

class Tree1 < Wx::App
  def on_init
    # Create frame
    topframe = Wx::Frame.new nil, :title => "TreeCtrl Example"
    # Create TreeCtrl widget
    tree = Wx::TreeCtrl.new topframe,-1, Wx::Point.new(20,20), \
       Wx::Size.new(100,200), Wx::TR_HAS_BUTTONS + Wx::TR_SINGLE
    # Render the window
    topframe.show
    # Add root and items to TreeCtrl
    rootid = tree.add_root("foo")
    id1 = tree.append_item(rootid,"bar")
    id2 = tree.append_item(rootid,"baz")
    # Default : expand all branches
    rootid.expand_all
  end
end

Tree1.new.main_loop

The call to "expand_all" or "expand" crashes Ruby 1.8.6
[i386-mswin32], I haven''t tried other OS''s nor other Ruby
releases.
Is there a workaround, or is it a known bug (haven''t found it in the
buglist) ?
Thanks
Blaise
