Outlook sometimes crashes when activating encrypted mail with (partial) non-encrypted appendix
Open, HighPublic

Description

Outlook crashed 2 times today when showing some encrypted mail with (partial) non-encrypted appendix was activated and the according message box pops up / is closed (not sure). Error log for 2nd crash appended, not sure if I captured the correct moment.

Also, this doesn't happen regularly. I tried a lot to actively cause the crash and didn't manage. But I did manage to make the colors from the "Vertrauen" (green) and "Verschlüsselt" (blue) bars disappear one time, don't know how.

Hi,
as usual, thanks for your help.

From the log I can't see any Problem but it also does not capture the decrypt. The log only shows that Outlook is querying us for our UI code. And then you open the options dialog. Then the log ends.

It would be great if you could activate log level +trace and when it crashes again send in the last 1k lines (If you prefer, privately to aheinecke@gnupg.org). Data does not need to be included and I think that our pseudonymization of the logs is currently complete. So it should not include any personal data.

In the meantime I'll produce me some mails where the attachments are not encrypted and try to reproduce this issue myself. We have so few crashes nowadays (hurray) that I give every one high priority.

That the colors dissapear is sadly a known issue for me, I also do not know how to reproduce it, except by switching quickly between mails. I think there is a problem with latency regarding changes in the data model and updating the GUI. But that is a different issue.

Thanks!
Andre

Hi Andre,

this should be the correct log!

Hi,

Sorry for the delay, I was on my summer vacation ;-)

The log is interesting. From the log I think that I can see a reference count error. That would also explain some "randomness" about the crashes. I'll go through the code to find it.
