This is ubuntu's problem I don't care much about, but they need to
verify the keys are signed.

The k at k contains a subkey colliding with ubuntu's key 3F272F5B.

The order of importing the keys seems important and in one case a
self signature is reported as other user, in the other case a selfisg
is reported as bad signature from wrong user.

I suppose if the colliding key is first it makes the other key unusable.
