When verifying a signed text (as does tests/gpg/t-verify test), gpgme_op_verify returns a hard error (General Error), instead of a proper signature mismatch report by gpgme_op_verify_result. This is exposed by tests/gpg/t-verify test failure. Upstream have fixed this bug in 1.10 branch: https://git.gnupg.org/cgi-bin/gitweb.cgi?p=gpgme.git;a=commit;h=9aa33a99701e189d7fc0ff7322fc9e21e35b73fa Reproducible: Always
