Opening settings presenter raises Gdk Critical log

[demarey]

In Pharo LAuncher GTK, when clicking on Open settings button, an error is raised on the console:

(Pharo Launcher:82070): Gdk-CRITICAL **: 10:52:05.721: gdk_toplevel_get_state: assertion 'GDK_IS_TOPLEVEL (toplevel)' failed

indeed, but even if is critical, it is just a warning (it will not annoy, for a moment ;) )
