Attempts to register same type multiple times.

Description
I've got a class derived from Gtk::TreeModel::ColumnRecord defined in a plugin.
If I load the plugin multiple times, Glibmm gives this error:
glibmm-WARNING **: file value_custom.cc: (Glib::custom_boxed_type_register): The type name `glibmm__CustomBoxed_N3cas13_MachineCoordE' has been registered already. This is not supposed to happen -- please send a mail with detailed information about your platform to gtkmm-list@gnome.org. Thanks.
I don't have a test case worked up, but I might be able to work one up later if I have time.
