Looks like you are updating the TextView buffer from other place different than
the main thread, Gtk is thread aware but not thread safe, it can't handle GUI
updates outside the main thread. What I've done is "watch" a variable in the
child thread and update (in the main thread) the GUI if required.
you can use gtk.events_pending() in a loop to make sure the gui is not frozen
when checking the child thread.
while True:
# check_thread
# update_gui
while gtk.events_pending():
gtk.main_iteration_do(False)
