gpgsm --sign outside of Emacs does work without any problems.

I actually have no problems signing with S/MIME also inside Emacs (as
far as the passphrase has been cached). And I have no problems signing
with PGP (pinentry loopback works fine then).

So it looks like something that affects exclusively pinentry loopback
while signing with S/MIME (actually you will see this e-mail signed with
S/MIME. Basically I try to sign it, if I get the error because the
passphrase was not cached, I simply sign a region with PGP (which asks
me correctly for the passphrase and it gets cached, and then I have no
problem signing and sending the message).

I really have no clue what could be going on...

Thanks,
