Thanks,
I edited the task and now you can edit it too.

Hi,
could you please change the edit policy back to all users so that I can change the status of this task?

I think this might be the issue with High DPI support problems. T4819 which is not yet released.

The problem is with the code for T3656

Thanks for the report. I can reproduce this by replying to S/MIME enc & sign mails.

@Angel: The mail server log showed 0 bytes for the affected messages.

Are they actually zero-byte mails, or is the content mungled as an attachment? (which those replying probably overlooked, and would still be hard to interpret, as it would containe MIME parts)

The required libgpg-error 1.38 has now been released.

I observe the same problem since I installed gpg4win 3.1.11 (german) in Outlook, Office Professional Plus 2019, Version 2004: Occasionally "zero byte mails" are sent by replying to an s/mine certified and encrypted mail. In my case the option s/mine support is disabled in GpgOL menu.

This was implemented 0d2db8b81ab24e2ab02d7ba6832cabd07b72f852 in Gpg4win-3.1.11 but does not work reliably.

Closing with Info Needed.

I'm moving this from testing to open again. Especially the deletion is an issue. I had a report that even for a sent mail Outlook.com also stores an unencrypted variant in the "Trash Bin".

Works nicely

This was released in December 2019

"Wyszukaj na na serwerze..." has been changed to "Wyszukaj na serwerze..." and should appear in the next release of Kleopatra.

Thanks for the logs. I can see the crashes, but I can't make heads or tails of them. We crash in completely valid code. I really don't want to play the blame game here but to me this would be explainable if there is an issue with refcounting in the GFI plugin that would release the IMessage or ISecureMessage MAPI Object from the ItemLoad event once to many. In that case the object we work with might be deleted at random times and that would explain it.

I added the log file.

It'll be fixed soon. Please use https://sourceforge.net/p/kdei18n-pl/mailman/kdei18n-pl-uwagi/ next time.

could you please go into the GpgOL setting and under "Debug" turn on logging on the highest level (+code trace) and then reproduce the crash and add the log here?
Including Data should not be needed so you can keep that checkbox unchecked to avoid having mail data in the logs.
This might help us to see where and why the crash occurs.
