How does one get this to happen?  

Is it only a problem if two threads race to pass the same type_name to
g_type_register_*()?

Or if a library defines a shitty foo_get_type() without the g_once
magic from G_DEFINE_TYPE(), and gets called from two threads?

Nah, it's Rust-only magic to deal conveniently with passing/getting
arguments to/from glib.  Where the GObject introspection annotations
say transfer-full, you can call String::from_glib_full(ptr_to_c_char);
where they say transfer-none, you can call String::from_glib_none(ptr).
 It doesn't register new GTypes at all.
