SUMMARY
Configure aqbanking without a customerID crashes KMyMoney. It's most likely an aqbanking bug (AH_User_SetSelectedTanMethod: Assertion `u' failed).
But KMyMoney should not crash. 

STEPS TO REPRODUCE
1. have a vanilla KMyMoney installation, no ~/.aqbanking folder
2. click settings -> configure aqbanking -> create user
3. select hbci aqbanking
4. setup pin/tan
5. fill in a valid bank code (12030000), bank name (DKB), server url (https://fints.dkb.de/fints)
6. fill in a valid user name and user id, keep customer id blank!
7. accept certificate
8. fill in a valid pin
9. select a tan method (e.g. chiptan)

OBSERVED RESULT
KMyMoney crashes

EXPECTED RESULT
KMyMoney should give me a reasonable error message if something in the backend fails.

Comment 1 Jack 2025-10-12 15:53:15 UTC 
Does this now work with the latest versions?  I don't know if OpenSuse provide 5.2.1, but if not, you can try Appimage, Snap, or Flatpak.
Comment 2 Thomas Baumgart 2025-10-13 13:58:39 UTC 
I think I fixed this upstream in AqBanking. This is incorporated into versions 6.5.12 and above (current is 6.6.4). I therefore close it here as fixed upstream.

Here's the commit message:

> Fix crash when function is called without user
> 
> Changes made in commit 964e0a3d cause dlg_edituserpintan::_fromGui to be
> called without a user to check the data in the dialog for validity. This
> causes the following crash due to usage of NULL pointer:

> Zusicherung »u« nicht erfüllt.

> Also, in some erroneous cases, the return code is not provided when the
> quiet mode (no GUI activity) is selected.
> 
> This change corrects all of the above.
