Re: GtkTextBuffer crashes

In short, I think that's it much better if you don't make GTK calls
from the second thread, it's a sure-fire way to avoid multi-threading
UI issues.  But, all you need to do is,

1. wrap gtk_main(), ie.,

  g_thread_init (NULL);   // Add this line
  gdk_threads_init ();   // Add this line
  gdk_threads_enter ();   // Add this line
  gtk_init (&argc, &argv);
  gtk_main ();   // Add this line
  gdk_threads_leave ();   // Add this line

2. In your second thread, make sure that every gtk/gdk call is wrapped,

  gdk_threads_enter ();   // Add this line
  gtk_do_something();
  gtk_do_something_else();
  gdk_threads_leave ();   // Add this line

Do NOT wrap GTK calls in the main thread, only in the second thread
