Sentry Crash Report:

Description Geo Chura 2017-03-28 18:29:10 UTC
Application: kontact (5.4.3)

Qt Version: 5.7.1
Frameworks Version: 5.32.0
Operating System: Linux 4.10.5-200.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed: moving mail folders within Kmail

- Unusual behavior I noticed: when using the move command, the order of the folders reorders without user input. It then reorders again reverting to the original ordering scheme when the move command is selected another time.

- Custom settings of the application: The Breeze-Dark appearance theme was selected in each of at least five similar crashes (on different installs of Fedora 25) and this setting seems to create additional instability in the Plasma 5.8.X desktops.

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 Michel 2017-05-09 08:57:44 UTC
Hi, 

I've got the same problem. I went to import my backup mail to my new kontact/kmail interface due a crash. I can not move my old mail folder to a new one.
I did many akonadi_ctl restart no issue.

KDE Frameworks 5.18.0
Qt 5.5.1 (built against 5.5.1)
Ubuntu 16.04.2 LTS
Comment 2 Michel 2017-05-09 11:45:16 UTC
HI

Fixed after the command  'akonadictl fsck'

Sorry to spam and borring.

Thanks for your support
Comment 3 Denis Kurz 2018-01-31 16:09:59 UTC
You might want to consider if this was caused by a Qt bug that was resolved fixed in 5.8, as described in Bug 361895, Comment 1.
Comment 4 Michel 2018-02-01 10:20:32 UTC
Hi Denis 

I don't know if you're telling me, do you ?

I mean I've got the problem on Kubuntu and the update gave me an issue.
By the way I did not realize that's this case of KDE bugtracking is about Fedora platform

Apologize
Comment 5 Denis Kurz 2018-02-01 10:46:27 UTC
Michel, my comment was just meant as a suggestion to anyone who investigates this bug, not to someone affected by it. The problem described by this report might be caused by a bug in Qt, not a bug in KDE. I found a Qt bug that might be the culprit, and this bug was fixed in 5.8.

Jugding from Comment 3, you are not affected any more. It would be interesting to know if anyone with Qt 5.8 or later is affected.

Sorry for the confusion.
Comment 6 Justin Zobel 2020-12-17 05:33:55 UTC

Comment 8 George 2021-01-02 08:40:53 UTC
Hi and thanks for getting in touch. 

The bug was reported 3+ years ago, my sense is that the problem was
fixed, or at least, significantly improved. 

I spent a lot of time with Kontact and learned a fair bit about the
app, but I finally abandoned it in favour of Evolution, which  runs
well and integrates perfectly with my KDE Plasma Breeze Dark themes.
Evolution offers many of the features that Kontact provided to me as a
single user. Evolution is just much easier to configure, and thus, more
reliable than Kontact.

All the best, George
