Weird behaviours with validity

[Ximin Luo]

(new,mine) If I import my public key [1] into an empty homedir and set ownertrust to ultimate, the validity (on all UIDs) is also set to ultimate.

(old,mine) If I do the same thing with my pre-existing homedir, the validity (on all UIDs) is set to "undef" for some reason.

(old,other) If I do the same thing with my pre-existing homedir, but with (e.g.) dkg's key [2], some UIDs are "undef" and other UIDs are "ultimate".

(new,other) If I do the same thing with dkg's key in an empty homedir, the validity is set to ultimate.

The validity also remains unchanged as "undef", even if I import a masterless secret key. (But GPG 1.4 seems to set the validity to "ultimate", in the same situation.)

All of these behaviours are pretty weird. I couldn't find a good explanation of them in the docs.

At the end of the day, I just want GPG to recognise my own key (with secret subkeys available, secret master key not available) as "ultimate" validity. How do I do this?
