Description Laurent RINEAU 2017-11-29 10:01:49 UTC

Application: kontact (5.6.3)

Qt Version: 5.9.2
Frameworks Version: 5.40.0
Operating System: Linux 4.13.15-300.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"

-- Information about the crash:
- What I was doing when the application crashed:

I was just reading my mails. I think the crash occurs sometimes just when one clicks on an email in the emails list of a folder. Actually, in all my tabs, I display several folders at once. That may be relevent.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Laurent RINEAU 2017-11-29 10:03:58 UTC

That is indeed very similar to old bug #328222, where I posted a comment: https://bugs.kde.org/show_bug.cgi?id=328222#c4

But it is now with a recent version of Kontact/Kmail, and it occurs several times a day.

Comment 2 Justin Zobel 2020-12-17 05:32:34 UTC

Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.

Comment 3 Laurent RINEAU 2020-12-17 08:17:50 UTC

That was indeed long ago. It works very well, now.
