[pulseaudio-discuss] Vala arrays broken?

I wanted to enumerate the ports on the cards through vala today. I
quickly found that the vala binding was not up-to-date, so I added
fields for that (see attachment).
However, to be able to access the card ports, I needed to do two things
differently from how the existing arrays look:
1) I needed to add this line to indicate the length of the array:
[CCode (array_length_cname="n_ports", array_length_type="uint32")]
2) I needed to add a question mark to indicate these are
pointer-to-pointers (pa_card_port_info **). Otherwise vala would think
they are simple pointers (pa_card_port_info *) and fail with a segfault.
This raises the question if anybody ever has used these arrays before
and got them to work, or if I should just change this on all arrays
(with pointer-to-pointers)? Anybody who knows?
