How to restore kgpg keys?

[Vinicius]

Hello,

I did do a backup of my home dir and then restored the ~/.gnupg/ to a 
new home dir (with the same username and permissions).
So, I can use gpg normally, but the kgpg has none keys. Even if I try to 
import keys to kgpg (from a previous gpg --export command), it does nothing.
How to import the gpg to kgpg or how to do to both work together, please?

TIA,
Vinicius.
