Hello,

The minimal test case seems to be to expire a key and then import its
revocation certificate. .45 exits with 2 instead of success.
--------------------
#!/bin/sh

MYGPGHOME=`mktemp -d`

cp -a /tmp/ostree-2024.8/tests/gpghome/* ${MYGPGHOME}/
gpg --homedir=${MYGPGHOME}  --version
gpg --homedir=${MYGPGHOME} -K > /dev/null

gpg --verbose --homedir=${MYGPGHOME} \
	--quick-set-expire 5E65DE75AB1C501862D476347FCA23D8472CDAFA seconds=1
echo DEBUG quick-expire exit status $?
sleep 2
gpg --verbose --homedir=${MYGPGHOME} --import \
	/tmp/ostree-2024.8/tests/gpghome/revocations/key1.rev
echo DEBUG import rev exit status $?
rm -rf ${MYGPGHOME}
--------------------

Given that gpg 2.4 does not behave this way I think this is probably not
intended.
