Might be that it is too late, but I find it at least curious that the following few lines seem to be causing a segmentation fault if and only when compiled with gcc's optimization, even "-O1"!
settings_dialog = gtk_dialog_new_with_buttons("gatotray Settings"
, NULL, 0, GTK_STOCK_CANCEL, FALSE, GTK_STOCK_SAVE, TRUE, 0);
g_signal_connect(G_OBJECT(settings_dialog), "response", G_CALLBACK(gtk_widget_destroy), NULL);
g_signal_connect(G_OBJECT(settings_dialog), "destroy", G_CALLBACK(settings_destroyed), NULL);
GtkWidget *vb = gtk_dialog_get_content_area(GTK_DIALOG(settings_dialog));
GtkWidget *hb = gtk_hbox_new(FALSE, 3);
gtk_container_add(GTK_CONTAINER(hb), gtk_label_new("Background:"));
GtkWidget *cb = gtk_color_button_new();
gtk_container_add(GTK_CONTAINER(hb), cb);
gtk_container_add(GTK_CONTAINER(vb), hb);
This is the backtrace:

... settings.c:24 is exactly the first line listed above, seems like "gtk_dialog_new_with_buttons" is the culprit...
Versions:
gcc: 4.4.3
GTK+: 2.20.1
BTW, forgot to mention that commenting out certain lines after the conflictive call prevents it from happening. Particularly the line with "gtk_container_add(GTK_CONTAINER(hb), cb);"
I tried almost all suitable combinations of GtkTypes/GTK_MACROS, it makes no difference.
