That's what I get on the console at the time of the crash:

Any help I can give about this issue?

This even happens, if I just start a new transaction, choose the bank account from which I want to send the money with HBCI and edit the "purpose" field (Verwendungszweck). If I then hit the "cancel" button, kmymoney crashes. Not sure if that is the same crash...

Can you provide a backtrace for the crash happening after entering the purpose field and pressing Abort? If you don't know how to do that, please let us know.

debug trace from gdb

This is the debug trace I got from gdb. Does that help?

Unfortunately, no :( kmymoney is mentioned only twice but not in a reference to some KMyMoney code. Would be interesting to see if a recently added patch (https://invent.kde.org/office/kmymoney/-/commit/30c9dd75) solves the problem

Is there any chance, I can improve the output of the backtrace?

I tried to build kmm locally. However, I am not sure, if I did it properly. I did:

cmake -B build -S . -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_WITH_QT6=ON -DBUILD_SHARED=OFF
cmake --build build

but when I run kmm, it shows messages like

kf.coreaddons: The plugin "/usr/lib64/qt6/plugins/kmymoney_plugins/reportsview.so" explicitly states an 'Id' in the embedded metadata. This value should be removed, the resulting pluginId will not be affected by it

Does it still take the globally installed plugins? How can I prevent this?

And right now it crashes with
terminate called after throwing an instance of 'MyMoneyException'
  what():  Illegal settings when calling doForecast. Settings must be higher than 0 /home/svater/kdecode/kmymoney/kmymoney/mymoney/mymoneyforecast.cpp:1027

The new crash may be related by a mixture of the installed and self-build version. I never had full success to run two different versions side-by-side. Another cmake option I would add is -DCMAKE_BUILD_TYPE=Debug and then run the application under gdb control to get access to backtraces.

I am not sure, which infos you would like to have. The crash persists also with a current install from git.

Would it make sense to add some manual output into the code to see at which point the crash happens? I never did this in such a complex program....

I wonder, if the crash could be related to a problem reported last year: https://invent.kde.org/office/kmymoney/-/commit/21029587f2d43cd964f711d0e76361830d090083

I just checked if the self compiled kmymoney really uses its own plugins and it seems that it still used the ones from the system (rpm package).

So I hard copied the compiled plugin files to the location of the system plugin files. A first test shows that the crash is not present any more and it seems to be fixed. I am really sorry for the noise. I set the status to RESOLVED.

Is there already some expected date for a new version of kmymoney, which has the fix included?

Setting QT_PLUGIN_PATH to the lib dir below the build root can help here. 

Then run 

gdb <build-dir>/bin/kymoney 
b main
r
info sharedlibrary

to see the list of loaded plugins and there location.

Well, since you build KMyMoney yourself, you can simply remove the distro provided package and replace it with your own using the following commands.

$ sudo rpm -e kmymoney

and then checkout the 5.2 branch and build it using

$ cd <whereever-your-kmymoney-source-is>
$ rm -rf build     # get rid of previous build
$ git switch 5.2   # switch to the stable branch
$ git pull              # get the latest fixes
$ cmake -B build -S . -DCMAKE_INSTALL_PREFIX=/usr -DBUILD_WITH_QT6=ON
$ cmake --build build
$ cd build
$ sudo make install
$ cd ..

to uninstall such a version do inside the source directory

$ sudo xargs rm -rf < build/install_manifest.txt
