clutter_init() fails under normal circumstances like being unable to open a display connection, so it shouldn't be handled with g_error() producing a core dump. Clutter consistently produces an error message when clutter_init() fails, so we don't need to print out any error message. https://bugzilla.gnome.org/show_bug.cgi?id=643910
