@werner For rCd5e3cbfd , my mingw (GCC version 14) complains about the function-return-type difference of the prototype with GetProcAddress.

That RFC is Experimental anyway

Fixed and backported for VSD 3.4.

Ranking as discussed with @ebo

The root cause is that opening the details reloads the certificate. This triggers a change of the key cache. And that triggers are reload of the group.

This also happens in vsd 3.3.2 and gpg4win-5.0.0-beta413 @ win11

Scute fixed in rSc3dc9c581631: w32: Use CSIDL_COMMON_APPDATA if available.

Additionally to the issue Andre cited years ago, we also did some changes to fix other how signed/encrypted mails are shown, which are also relevant for the inbox. This should be fixed.

Here is my proposal:

It would be possible as a workaround in Kleopatra to show any identical entries only once. Saving after that will not add any more entries.

Okay, forward porting that patch is the easiest solution. Actually this is not enough: Users of Libgcrypt also need to make sure that the new sysconfig dir has the right permissions. That's a part for the installer and concrete ACLs may differ.

Good catch. My guess is that get_uid_for_sender returns the last matching UID without checking for revocations. The matching was done on the mailbox part only. For reference:

Here is my analysis.

I can't reproduce this on gpg4win-5.0.0-beta413 @ win11.

I examined the code of gnupg_sysconfdir in gnupg/common/homedir.c, if we could factor out things to gpgrt, so that something like gpgrt_fconcat with GPGRT_SYSCONFDIR can be implemented.

git checkout gnupg-2.5.14, reverted the commits 46f4cb66125ee34e87e592cc02d38daead3427af and 0cc7759ed5a3890b4e28563a6b5e97f3aa551530, recompiled, and the error message gpg: keydb_search_first failed: SQL error no longer appeared. Also, in /root/.gnupg/public-keys.d/, the two files pubring.db.lock and .#lk0x0000... are present.

Looks good to me on gpg4win-5.0.0-beta413 @ win11.

Let me explain about the change rG57affc4e98ab.

Additionally, in the /root/.gnupg/public-keys.d/ directory, the two files .#lk0x00007fdcb40043b0.b02bef684bbe.5108 and pubring.db.lock are missing.

gpg was compiled with the latest version of SQLite3 at the time as its own private library, without linking against the system's libsqlite3.so.
The sqlite3 CLI is the version that comes pre-installed with Ubuntu 22.04.5.

Can you please schek which Sqlite version you have installed? I have not seen this on my system.

Interesting. What SQlite version are you using? To see the exact reason and you have a copy of the old pubring.db, please add

Applied the change to master: rG57affc4e98ab: common,agent,dirmngr,kbx:w32: Synchronous spawning daemon process.

I applied a change with GPGRT_ATTR_NONSTRING to master, since 2.6 branch now requires newere gpgrt.
Fix is rGcad79e542d85: agent,common,dirmngr,tests: Silence warnings of a compiler.
