pinentry doesn't work with Emacs anymore

Hi!
A short while ago, pinentry-gtk2 was removed from
app-crypt/pinentry. Around the same time, app-crypt/gnupg was
updated. Since then, I can not use the gpg-agent from whithin Emacs
(--deamon) anymore. When I commit something with Magit, I get no
password dialog but this error message instead:

error: gpg failed to sign the data

After I add the key to the agent in another way (with `echo "test" | gpg
--clearsign` for example), it works in Emacs again. So it seems that
there is something wrong with my pinentry setup.

I tried pinentry-gnome3 and pinentry-qt5, it makes no
difference. GPG_AGENT_INFO is known to Emacs.

This is my ~/.gnupg/gpg-agent.conf:

default-cache-ttl 43200
max-cache-ttl 86400
default-cache-ttl-ssh 21600
max-cache-ttl-ssh 86400
pinentry-program /usr/bin/pinentry

Does anybody know what the problem might be?

Kind regards, tastytea

I have the same entry in my gpg-agent.conf and it works fine, but I do not use
emacs.

My /usr/bin/pinentry is linked to pinentry-qt:

$ ls -la /usr/bin/pinentry
lrwxrwxrwx 1 root root 11 Jun 21 2019 /usr/bin/pinentry -> pinentry-qt

You could set this manually, or with eselect, or I think your desktop
environment will set it for you.

I did set it with eselect. pinentry works fine when I use gpg in the
terminal. It seems to be a problem with gpg inside Emacs.
