Description Taner 2020-12-24 14:37:50 UTC 
Application: kontact (5.16.0 (20.12.0))

Qt Version: 5.15.2

Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

Quite often when I start Kontact I receive a crash notification on my desktop. In some cases there is no new window and I need to relaunch Kontact to use it and in some cases Kontact window still show up after crash notification and I can use it as normal. It seems like akkregator session is in all cases crashed and needs to be restored or dismissed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

Comment 1 Philippe ROUBACH 2021-02-01 05:54:32 UTC 
Created attachment 135344 [details]
New crash information added by DrKonqi

kontact (5.16.1 (20.12.0)) using Qt 5.15.2

- What I was doing when the application crashed:

I have just launched kontact.
Dr konqui opens a crash report window and offers to me to restart kontact
But kontact starts normaly.
I can use kontact. I don't need to start up kontact again.

Comment 2 Philippe ROUBACH 2021-02-01 06:14:13 UTC 
It's not a random phenomenon.
Each time I launch kontact I get a crash.

I can't access to any mails. When I click on a mail I get a message saying kmail is receiving the mail, be patient. I must wait about several mn before kmail displays or not mail contents.

Today the task to back up my mails stops saying it can't access to a mail.
Comment 3 Philippe ROUBACH 2021-02-01 06:25:49 UTC 
If I don't access to a mail in my "Personnel" folder in kmail local account
then
no problem to access to a mail in my imap account and to read them.

If I access to any mail in "Personnel" then I can't read this mail but also those in my imap account.
Comment 4 Philippe ROUBACH 2021-02-01 07:12:40 UTC 
i quit kontact
then
in konsole i execute

akonadictl restart

then

no more crash launching kontact.
no more problem accessing "Personnel" folder and to display any mail.
