Add the following line to your application:

GLib.Log.SetLogHandler ("Gtk", GLib.LogLevelFlags.All, new GLib.LogFunc
(GLib.Log.PrintTraceLogFunction));

That will cause a stack trace dump any time a Gtk log warning occurs.
We have an environment variable GTK_SHARP_DEBUG which automatically does
this for GLib-GObject warnings.  We probably need to add a similar check
for the Gtk log domain as well.
