I had the same problem a few days ago, and I've even found a solution.
One solution is to put threads_leave and threads_enter around the loop:
gtk.threads_leave()
while gtk.events_pending():
gtk.mainiteration(0)
gtk.threads_enter()
I don't know whether this is the correct solution, though. It works for
me in Sketch, but Sketch is single threaded but runs on a thread enabled
Python interpreter.
Alternatively, one could modify pygtk and put the leave/enter into the
wrappers for gtk_main_iteration_do and gtk_events_pending as I outlined
in my last mail.
I think that it's really a bug in gtk. The function gtk_main() puts
leave/enter around the call to g_main_run while gtk_main_iteration and
gtk_events_pending don't do that for the calls to g_main_iteration and
g_main_pending respectively.
