[Gtk-sharp-list] Gtk.Spinner doesn't spin (Gtk# 2.99.2)

[Stephen Brandt]

Hello everyone,

The Gtk.Spinner doesn't seem eager to spin using the gtk-sharp-3 
bindings. Even though I have set the obvious properties:
spinner.Active = true;
spinner.Start ();

Any ideas what's missing here or is it a just bug in the bindings? I've 
tested on systems running Gtk+ 3.8 and 3.10, on both it didn't work.

Thanks for your help,

Stephen
