The problem is here:

The code in the event handler is already running in the GTK thread.
Your code attempts to pass the code to the GTK thread from within the
GTK thread.
Gtk.Application.Invoke is only used within threads other than the GTK
thread (because GTK# is not 'threadsafe'). So, if you had a thread
called mythread, once that thread was started you would use
Gtk.Application.Invoke to access GTK objects safely.
