All mails touched by gpgol should already have a GPGOL_UID_DASL. So to replicate:

1. Send a new encrypted mail (e.g. Edward -> Ted)
2. Don't open that mail, but open the context menu: Move -> Other Folder ...
3. Select a subfolder of INBOX and click OK -> the mail is not moved

fix tested and confirmed with GnuPG 2.5.12 on windows 10

Looks good to me on gpg4win-5.0.0-beta369 @ win10

Tested with VS-Desktop-3.3.90.8-Beta and the test gpgol.dll from 2025-09-10 and the same test mail from the original report:
The spawning cycle does not occur any more. (Tested with Outlook setting "show as text only" and without.)

Note: If i set an invalid path in "Software\\GnuPG:Install Directory"

• the gpgconf -X output does not change
• the self-test Config File 'libkleopatrarc' fails with Error in archive definition tar: 'pack-command-openpgp' empty or not found

This probably can only be tested with signed releases?

Here are the messages and logs, when trying to open them:

Andre mentioned in 10721b1dccf4 that "Closing the mail this early might also have contributed to
endless loops of read + close" which is what we see here as well

Uses gpgme-2.0.0 with the above mentioned patches. I have seen no problems in my quick tests.

For the full fledged Windows installer see https://files.gpg4win.org/Beta/gpg4win-5.0.0-beta369/gpg4win-5.0.0-beta369.exe

Is that really the same bug? I would be interested in seeing a more detailed report. BTW, Windows or Linux? Used standard beta installer on Windows?

If this is indeed a bug it won't be fixed in gpg4win 4. Thus a test with gpg4win 5 beta is highly appreciated. It would also be interesting to see what what version of gpg comes with Git.
