If the filename embedded in the encrypted message differs from the filename Kleopatra uses (which is derived from the file system filename) Kleopatra will now show the filename. This should cover the case where users receive an "Attachment.pgp" and do not know what that is.

Can you open the command line (cmd.exe) and execute there: "gpg --passwd 6B05B09F" ?

I've recently moved from the Windows 7 system where I saw the problem to a Windows 10 system where Kleopatra works. As Windows 7 will no longer be supported by Microsoft, there seems little point in working on this issue, so I'd be happy if it was closed as Won't Fix.

Hi - that did the trick. The linked gpgol.dll loads without any issues. However the decryption of e-Mails don't work. I get the
"OpenPGP Encrypted message (decryption not possible) Could not decrypt the data: Unsupported protocol" error.

see: https://wiki.gnupg.org/TroubleShooting#Manually_update_GpgOL_to_a_beta

This is very strange, common to all the crashes in the log is that they happen while a keylisting is running and before the first key from that keylisting is returned. But this could be a red herring because the keylisting is always started immediately in a background thread and so it would be normal that if the crash occurs immediately that it would still be running. The keylisting code is extremely similar to Kleopatra though. So I don't understand why Kleopatra would then work for you.

Since I configured call tracing the running O365 Client dies immediately after activating the addin. Same happens now if I activate the addin.
Anyways, here is the log.

Thanks for the report. Log looks not unusual.

It's better to have a new Task for this as I explain in T4402

I'm new here, therefore I'm unsure whether this posting is correct at this position.
Within my organisation we have ongoing troubles with the error described here, with windows version 3.1.3 there is no such button "force decryption" as documented here.

Hello，
i am sorry. it really wasn't a high priority Bug, I just want to get your attention（^_^）.

I'm not sure yet where the bug lives. It's either in GPGME's editkeyinteractor that ignores the error / cancel or in Kleopatra itself. I'll have to look into it. Btw. I do not think that this should have high priority because it is not a new regression and while it is a Bug and wrong it is not really harmful.

Hello,
I've opened T4395 for this to keep better track of it as this task was about another issue.

From a comment in T3990

Hi，aheinecke。my kleopatra version is "kleopatra Version 3.1.4-gpg4win-3.1.5".and when change expiry date, i enter a wrong passphrase or choose "cancle". it shows successfully. what can i do for solve this question. thanks.

The dialog is improved and simplified now.

Thanks for the report. Indeed a bug. Will be fixed in the next release.

This was fixed.

Thanks for reply and clarification, regards danny

Thank you for the report. Sadly this is a long standing bug that is still not fixed. We hope to address this in a future version.

Even with the logging changes this still happens. I just retested it. Can't run Kleopatra on Linux with GPGME_DEBUG=9.
