 Maestro trunk (2011-10-24)
 OS: Windows XP SP3

 In layer stylization if I try to change rules order using the buttons I
 receive the following error (translated back to english, so wording may be
 a little different)

 {{{
 System.InvalidCastException: Cannot cast an object of type
 '<get_Rules>d__0' into type 'System.Collections.IList'.
    in
 Maestro.Editors.LayerDefinition.Vector.Scales.ConditionList.MoveSelectedRule(Boolean
 down) in

    in
 Maestro.Editors.LayerDefinition.Vector.Scales.ConditionListButtons.MoveRuleDownButton_Click(Object
 sender, EventArgs e) in

    in System.Windows.Forms.Control.OnClick(EventArgs e)
    in System.Windows.Forms.Button.OnClick(EventArgs e)
    in System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
    in System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons
 button, Int32 clicks)
    in System.Windows.Forms.Control.WndProc(Message& m)
    in System.Windows.Forms.ButtonBase.WndProc(Message& m)
    in System.Windows.Forms.Button.WndProc(Message& m)
    in System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message&
 m)
    in System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
    in System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg,
 IntPtr wparam, IntPtr lparam)
 }}}

 What is bad of this bug is that UI does swap rules so user think that
 despite the error the reorder succeeded.

 Then  obviously layer stylization is different than expected looking at
 the UI.
