I noticed that this morning (after a reboot) it was looking for a different 
socket ...

Why is it trying to call /usr/bin/pinentry-qt?!  

   `ERR 67109133 can't exec `/usr/bin/pinentry-qt'

Is this a valid binary these days, or an older qt3 version?  I think it should 
be /usr/bin/pinentry:

$ ls -la /usr/bin/pinentry
lrwxrwxrwx 1 root root 12 Feb 24 07:01 /usr/bin/pinentry -> pinentry-qt4

Please note that the: "Please+enter+the+passphrase+to+unlock+the+secret+key" 
does not show up on the screen even when I use the gpg -vv option.
