[Vala] How to pass null to Gst.init?

["marcin saepia net" <marcin saepia net>]

Hello,

I would like to pass NULL to Gst.init. I intentionally do not want to pass
argv.

It is defined as

void Gst.init (ref unowned string[]? argv)

but if I pass null it throws

error: Argument 1: Cannot pass null to reference parameter
      Gst.init(null);

despite parameter type having "?"

How can I achieve this?
