This is all OK.

I think I got that wrong, because now it ignores the signate if the ARE
Mime headers and does the check when they are absent.

Actually after trying again (and removing the Mime headers) it checks OK.
Including the original that I thought failed. I can't understand what
happened. I did not upgrade VM in the meantime, I haven't even restarted
Emacs since.

I do have another message that I received from someone else, that fails
with vm-pgg but succeeds with mailcrypt. However it contains non-ASCII
characters without giving proper Mime headers, so that may just be a
problem with the character encoding.
