The meta data type descriptor must set .get_gtype only for
GObject properties which are of type int or uint. That is, when
the enum type cannot be automatically detected.
However, NM_SETTING_SERIAL_PARITY is a g_param_spec_enum()
of type NM_TYPE_SETTING_SERIAL_PARITY, so setting the get_gtype()
hook is wrong and leads to a crash
$ /bin/nmcli connection add type gsm autoconnect no con-name t ifname '*' apn xyz serial.parity 5

Segmentation fault (core dumped)
That is because the enum property setter does:
»···if ( has_gtype
»··· && NM_IN_SET (gtype_prop,
»··· G_TYPE_INT,
»··· G_TYPE_UINT)
»··· && G_TYPE_IS_CLASSED (gtype)
»··· && (gtype_class = g_type_class_ref (gtype))
»··· && ( (is_flags = G_IS_FLAGS_CLASS (gtype_class))
»··· || G_IS_ENUM_CLASS (gtype_class))) {
»···»···/* valid */
meaning, it only allows "has_gtype" if the native "gtype_prop" is
G_TYPE_INT or G_TYPE_UINT.
