You are correct, indeed now pgg-sign-region and pgg-encrypt-region
work! Thank you very much. However and there is a big however when I
use (mml-secure-message-sign-pgpmime) which uses that function

Then the signing seems to be ignored, that is the tag 
<#secure method=pgpmime mode=sign>

 is inserted as it should, asked for the passwd but then nothing
happens.
Shall I debug (mml-secure-message-sign-pgpmime)?

I am very puzzled now. As I said before vm-pgg works. So the culprit
seems to be mml-secure-message-sign-pgpmine, what other function
could I use ????
