[Mono-list] Gtk objects

[Tomas Olofsson]

Hi
Thanks for the help, I tried to use

Gtk.Application.Invoke (delegate {
    statusbar.Push(1, "Done");
});

just to see if it worked in a method not called by the gui-thread, but I 
get an exception:
Unhandled Exception: System.NullReferenceException: Object reference not 
set to an instance of an object
in <0x00083> ClientGUI:ShowSearchResults ()
.
.
Is there something else I must do to make Invoke work more than the 2 
lines above?

If you are changing from another Thread different than main see the
Responsive Applications article[1] for getting a solution.
