GtkWidget is a subclass of GObject (of course not in C++
sense, but in GObject type system).  The line

    gobject=(GObject *)gtk_window_new(GTK_WINDOW_TOPLEVEL);

contains nothing that could produce the errors above (unless
something else is seriously messed up).  Try to create
a minimal test case that reproduces the errors, you should
find the real source of the problem along the way -- if not,
post it.
