No need to stand on ceremony, that user was me. :)

I had originally created a key with an expiry and then changed it
rather than generating fresh keys (had my reasons for doing this bad
thing at the time), and I assumed the problem was a stray old version.

Could you verify that the key you have now is set to expire "never"?

This is starting to sound like an Evolution issue... either Evolution
"mis-flagging" good signatures from not fully trusted keys, or somehow
picking up on keys signed with other keys that have expired. You can
sign a key without assigning ultimate trust, and make a key trusted
without signing it. Doing either one arbitrarily is unwise. ;)

Trust can also be "inherited" from the owner trust assigned to various
signing keys, but the two are not synonymous nor is it an either/or
proposition. There's varying degrees of trust and owner trust that may
be "confusing" Evolution.

It *almost* sounds to me like Evolution has made some sort of policy
change that conflicts with a minor variation in the way you or your
"system" is managing keys. Check your own to make sure you haven't
managed to set some owner trust level less than Ultimate on your own
keys, for example.

If you could manually save and verify a problem message with the "double
verbose" switches set it might give some more clues too...
