This issue (bug id: T6481) is obviously fixed on master (commit
2f872fa68c6576724b9dabee9fb0844266f55d0d):

https://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=commit;h=2f872fa68c6576724b9dabee9fb0844266f55d0d

Will this be merged to STABLE-BRANCH-2-4 and part of the next release
(2.4.4?)?

Thanks.
