I'll try that. Not sure what g_log is, but I'll check with the
documentation. Thanks.

It doesn't matter which XML one use. The problem is with this code:

from gtk_generates.adb

   procedure Misc_Generate (N : Node_Ptr; File : File_Type) is
      function Build_Type return Glib.GType;
      pragma Import (C, Build_Type, "gtk_misc_get_type");

   begin
      Widget := Widget_New (Build_Type);   <-- Here it crashes 

Error message that I get in gdb is :

(gate:2999): GLib-GObject-WARNING **: cannot create instance of abstract (non-instantiatable) type `GtkMisc'

Program received signal SIGSEGV, Segmentation fault.
0x405e1a33 in g_datalist_id_get_data () from /usr/lib/libglib-2.0.so.0

But could you tell me what this Misc_Generate is supposed to do?
