Re: [Libguestfs] [PATCH] Non-working support for GObject Introspection.

Oh I see - this struct is actually attempting to create a GObject subclass containing a guestfs_h *. This definitely don't work, because of the mis-matched ptrs you mention. I thought you were registering 'guestfs_h *' itself as the type without the 'struct _GuestfsH' wrapper. This avoids GObject entirely introducing a new base type.
