[Gtk-sharp-list] cellrendererprogress confusion

I guess i should be a bit more specific than my initial hand wavy post....

So at the moment i have a...
  Dictionary<int, thing> thingDictionary = new Dictionary<int, thing>();

to that i have added a new object of type 'thing" (the 'thing' object
generates a number from 1 to 100 every second)....
  thingDictionary.Add(new thing());

i create my ListStore etc....
  Gtk.ListStore store = new Gtk.ListStore(typeof(thing));
  treeview1.AppendColumn("gear", new Gtk.CellRendererProgress(),new
  treeview1.Model = store;

The error I am getting is a "Cannot cast from source type to destination
type" at the line indicated.....

public void renderit(Gtk.TreeViewColumn col, Gtk.CellRenderer cell,
Gtk.TreeModel model, Gtk.TreeIter iter)
Error Here -> thing tt = (thing) model.GetValue(iter,0);
        (cell as Gtk.CellRendererProgress).Value = tt.time;

Hope that is not too confusing ;)
