Using BlueSwirl (http://art.gnome.org/themes/gdm_greeter/1201) and
another one based on the same Novell theme I can find the same errors:

Apr 22 08:23:52 peecee gdmgreeter[6338]: GLib-GObject-CRITICAL:
g_signal_connect_data: assertion `G_TYPE_CHECK_INSTANCE (instance)'

After contacting the upstream developer
(http://bugzilla.gnome.org/show_bug.cgi?id=527856), he suggested to
check with default themes and at least here (gdm 2.20.5-1) with the
three themes I've tried (Circles, Debian MoreBlue and Happy Gnome)
there are no errors in the logs.
