Ok, this is my first time in the emacs C code and I'm relatively new
to C so please be patient.  

1) Why does this function cause emacs to immediately close with 

Fatal error (6).Aborted

2) While developing, how can I make emacs be more helpful with its
   dying breath.



This is a handler for gtk drag and drop so the args aren't important
yet.  Just the three lines in it cause the crash ( i think).

static void 
jjr_drag_data_received_handler (GtkWidget *widget, GdkDragContext *context, 
		                      gint x, gint y, GtkSelectionData *selection_data, 
				      guint info, guint time)
{
    Lisp_Object filename;

    filename = build_string ("~/.bashrc");

    Fswitch_to_buffer(filename,Qnil);

}

Thanks for the help
