I've fixed this in git master here:
https://git.gnome.org/browse/glibmm/commit/?id=ece1463f6d796c7c74da1e9d37a4e69904a9706e

Until you can use that very latest version, you can use the C function
by calling connection->gobj() to get the underlying GDBusConnection*.

Unfortunately, it's hard to always get this right in our generated code.
