Exactly. The technicalities of this are way over my head but I think that segfault <segfa...@riseup.net> already investigated all of this while working on Tails Verifier [1] so he should be the one to talk to. But if I remember correctly, he's super busy with other things right now so maybe don't expect a quick answer (in the meantime, looking at the code might help).
