Description stakanov.s 2021-03-13 12:12:50 UTC 
Application: kontact (5.14.2 (20.04.2))

Qt Version: 5.12.7
Frameworks Version: 5.71.0
Operating System: Linux 5.3.18-lp152.66-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.2"

-- Information about the crash:
- What I was doing when the application crashed:
This time I was looking up a mail when the archiver complained: could not archive xxx folder. Now I closed contact, did run fsck, vacuum, restarted akonadi, no problem. 
But restarting Kontact induces the crash. 

Preminent for the segfault is a precedent session of Kontact prior to restarting it, which shows always (and it is quite frequent) the following errors in behavior

- Unusual behavior I noticed:
- messages are filtered correctly but shown only as "one unread message", not appearing in the list at all. 
- messages are not filtered correctly, instead stay in inbox, are filtered however if filtered manually.
- automated archiving fails complaining it could not archive a specific folder. The folder may change every time. Important is the errormessage, when restarting you encounter always this segfault. 

The program crashes only after having it shut down normally and restarting it. This happens whether restarting akonadi or not, fsck or not ect. So the mentioned actions before have just common denominator: stop of the specific function leads the user to restart the application. Restarting the application, the first time (not the second, there all is O.K.) the programm segfaults and throws this error. 
So what happens, happens actually before, leading to a restart and then to the segfault. 

This error is more frequently occurring after sessions that were suspended to disk as opposed to a newly started session. It is more frequent after awaking the system after suspend to ram.

New crash information added by DrKonqi

kontact (5.14.2 (20.04.2)) using Qt 5.12.7

- What I was doing when the application crashed:

Looked at a Planet openSUSE news feed – "Rancher 2.5.7 with container in Azure".
Then, began to write a new KMail mail - Bong ... [ On Easter Sunday - GRRRrrrr!!!! ]

And, this is 100 % reproducible – had the news feed reopened to grab the title for this report, closed it and moved to write the e-Mail I was about to write before -- Bonggg!!!! ...

The News Feed has to have been closed - from display in a new Akregator tab.
If it's open in a new Akregator tab, the segmentation fault doesn't occur.

If another Planet openSUSE article is opened and the closed - for example "Interview auf gnulinux.ch" - the segmentation fault also occurs . . .
