            Bug ID: 437545
           Summary: Segfault when connecting to bank account using
                    aqbanking in KMyMoney
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: rashid_usm at gmx.de
  Target Milestone: ---

Application: kmymoney (5.1.1)

Qt Version: 5.15.2
Frameworks Version: 5.81.0
Operating System: Linux 5.11.21-300.fc34.x86_64 x86_64
Windowing System: X11
Drkonqi Version: 5.21.5
Distribution: "Fedora release 34 (Thirty Four)"

-- Information about the crash:
- What I was doing when the application crashed:
I have a KMyMoney configuration where I have configured an account at a German
Sparkasse using aqbanking. I had last connected to this account successfully in
July 2020. I was still using Fedora 32 then. When I tried to connect to this
account today to update my ledger, it gave me a segfault after I had entered
the bank account PIN in the pop up window. 

I have tried it once more after forcefully deleting the lingering aqbanking
lock and had the same results.

The crash can be reproduced every time.

-- Backtrace:
Application: KMyMoney (kmymoney), signal: Segmentation fault
