            Bug ID: 443784
           Summary: Kmail crashes with segfault after not being able to
                    read (or better read again) the password of kwallet
                    manager
           Product: Akonadi
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: POP3 Resource

  Target Milestone: ---

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.
