Bug 443784

Application: akonadi_pop3_resource (5.18.1 (21.08.1))

Qt Version: 5.15.2
Frameworks Version: 5.86.0
Operating System: Linux 5.14.9-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.5
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:
Kmail opens normally, principal password accepted and mail retrieved. After some time delay, kmail is not able to open the password any more and shows an input window asking for it. 
If you do not give this password, you cannot retrive mail any more. So you retrive the password in wallet (were it still is). You input it into the request, all works and post is retrived...but, shortly after the program segfaults (in it's part pop server as it seems. 

- Unusual behavior I noticed:
sudden incapacity of reading kwallet , sometimes but not only mitigated by exeting the kwallemanager and restarting akonadi. 
when setting the password as contained in the wallet, in a high percentage (70% of cases) the pop server of kmail then segfaults and gives this output. 
This is repeatable. 

- Custom settings of the application:

mixed setting pop and imap accounts. 
The wallet previously was not presenting the problem, it could be a problem of the current TW KDE version.

The reporter is unsure if this crash is reproducible.
