Why does VLC insist on trying (and failing) to decrypt something that I've already decrypted?

I would like it if it would actually just, you know, play the effing movie. (But instead it crashes.)

This is on FreeBSD, but I do suspect that it is a cross-platform issue.

Segmentation fault (core dumped)

If libdvdnav decrypts, it is because the dvd reports it is encyrpted.

Could you elaborate a bit? How is that determined?

I can assure you 100% that the .iso in question has already been decrypted.

And anyway, what about the segmentation fault (and core dump) at the end? Obviously, _that_ is not very nice behavior. (But I guess that since I am working on FreeBSD, I will need to look into the causes of that myself.)

VLC decrypts because it needs to. That is all.

I'd guess the crash is due to your version of libdvdnav failing to parse the DVD. Update libdvdnav.
