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.

Key Approval dialog used by GpgOL (VSD only) looks good to me on gpg4win-5.0.0-beta357, Outlook LTSC Standard 2024 @ win10 (compliance mode):

How to test this? The follwing happens for an attachment of an encrypted mail on gpg4win-5.0.0-beta357, Outlook LTSC Standard 2024 @ win10:

Moving an encrypted message on Gpg4win-5.0.0-beta357, Outlook LTSC Standard 2024 @ win10 into an inbox subfolder of Ted.Tester and back works for me, too. Does this confirm, that it's working now?

i've included logfiles for gpg-agent and scdaemon with debug-level 10. the files include

Note that disabling Auto-preview is not the default and has only been implemented to work around severe performance degradation with certain MalwareAnti-Virus software.

In contrast to gnupg22 master did not proper show OCB compliance - not everything has yet been forward ported. But we can do so now and test master by setting GNUPG_ASSUME_COMPLIANCE=de-vs

Notes for testing (and maybe documentation update):

• A few features (?) of the old CSR creation have been removed:
  • The different choices offered after CSR creation (e.g. save to file, send to CA, create signing/encryption CSR with same settings, etc.) have been removed; now a file save dialog pops up when the CSR has been generated
  • Custom labels for the RSA key sizes ([CertificateCreationWizard]RSAKeySizeLabels); we use GnuPG's algorithm IDs as labels (items in the drop down box)
  • Custom key type ([CertificateCreationWizard]CMSKeyType); CSR creation supported (and still supports) only RSA as "key type"; by marking the config key as immutable one could force the creation of signing+encryption CSRs which makes little sense for S/MIME and might have been "copied" from OpenPGP key creation where forcing the generation of keys for signing & encryption does make some sense.
  • Specification of the CA's email address ([CertificateCreationWizard]CAEmailAddress); the generated CSRs are now always written to disk; the users will have to create an email themselves

We will do a new gpg4win beta soon.

@m.eik Could you please enable debug option for gpg-agent and get the log output for the crash?
