I'm resuming an old thread, sorry!

If I call hildon_gtk_window_take_screenshot() within the callback function
for the delete-event of the main app, just before gtk_main_quit(), it seems
that something has already happened to the main window: it complains that it
is not a GtkWindow (which usually is, as HildonWindow derives from it), but
a GdkWindow, and, of course, no screenshot were taken.
