I would check that the given arguments are correct, != NULL or GVIR_IS_FOO.

I would return TRUE on success, and error can be NULL (regular glib convention)

I suppose this is missing Christophe gconfig patches.

And I would verify that handle is == to current domain handle. If not,
we probably need to replace it or we need to throw an error. At the
minimum it would be nice to leave a comment after verifying that it is
safe to ignore return value.

(then send an updated patch for ack)
