I have added the fix as patch for VSD 3.3 because the commits that introduced this regression were also added as patches for VSD 3.3.

This is a regression that was introduced with T7759: Kleopatra: Notepad encryption with S/MIME fails.

Fixed. For VSD 3.4 this will also be fixed if gpgme is updated.

This is a bug in gpgme. gpgsm_assuan_simple_command only reads a single line before waiting for more data although there is a second line (ERR ...) ready to be read. gpgsm never sends more data because it has already sent its full answer. So gpgme waits forever.

Note that KWatchGnuPG isn't available on Windows.

Fixed. KWatchGnuPG doesn't modify GnuPG config files anymore. Instead one has to set socket:// as log file for the components one wants to see in KWatchGnuPG.

It needs to be clarified which kind of errors should be handled and which kind of S/MIME certificates should be allowed to be used for encryption:

• Valid certificates where the CRL check (or OCSP check?) fails
• Invalid certificates (e.g. because of incomplete chain/missing CA)
• Expired certificates

Do we have a test certificate for this? The certificate in T6702#176845 is expired.

Just a quick note: I wouldn't remove the gtk-2 pinentry unless you have made sure that all still supported long-term enterprise distributions (RHEL, SLES, Debian, ...) support something newer. I have kept the Qt 4 pinentry although Qt 4 is obsolete since ages because some people still used it.

Removing kleopatra tag since Kleopatra already does what's requested.
