Indeed.  I think we've got it solved, now.  I think it's a combination of
my error (revoked instead of deleted) and a bug in Turnpike's
implementation of PGP (encrypting to a revoked subkey).

To clarify (and I realise this part is waaaay off topic :)  ~I~ didn't
accuse Dave of these things.  I accused Dave of possibly having encrypted
to it maliciously and deliberately, which I have since retracted.  :o)

That's definitely part of it.  I shall remember to do so in future  :)

All the best,
