A good way to find out where this is happening is to do this after calling
gtk_init():

  g_log_set_fatal_mask ("g_log_domain_glib", G_LOG_LEVEL_CRITICAL | G_LOG_LEVEL_WARNING);
  g_log_set_fatal_mask ("Gdk", G_LOG_LEVEL_CRITICAL | G_LOG_LEVEL_WARNING);
  g_log_set_fatal_mask ("Gtk", G_LOG_LEVEL_CRITICAL | G_LOG_LEVEL_WARNING);
  g_log_set_fatal_mask (NULL, G_LOG_LEVEL_CRITICAL | G_LOG_LEVEL_WARNING);


Then the warning messages cause an abort() and you can use gdb to find out
exactly where it happened.

(By the way, should the log domain names be standardized?)
