Hi, Havoc, 
this was my previous email:

        I'm using gtk+ 1.2.6 and making a gtk application using glade 0.5.5.
        When choosing "gnome support" in the project options and choosing
        stock button layout for a push button, then my application crashes
        with the following messages:

        GLib-CRITICAL **: file gstring.c: line 331 (g_string_prepend): assertion `val != NULL' faile
        d.

        GLib-CRITICAL **: file gstring.c: line 331 (g_string_prepend): assertion `val != NUL
        L' failed.

        d.

        Gdk-CRITICAL **: file gdkwindow.c: line 1406 (gdk_window_get_visual): assertion `window != N

I found out the following:

1. Responsible for the "GLib-CRITICAL **: file gstring.c: line 331" messages is the call

        gnome_app_fill_menu (GTK_MENU_SHELL (menubar1), menubar1_uiinfo,NULL, FALSE, 0);

2. Responsible for the crash (IMLIB error) is the call

        Pushb_save = gnome_stock_button (GNOME_STOCK_BUTTON_OK);

Important: Both calls are located in the file generated by glade  ..._src.c
