I spent some time last night in a screen share session with JV. Some of the
time was spent on setting up the session. Once I could work on his box, we
started the analysis of what's going on.

I was wondering, why the kmm libraries show up in /lib64 when I expect them
at /usr/lib64 (where I also found them). Turns out, that on Fedora /lib64 is
a symlink to /usr/lib64. Ok, so not the cause of the problem.

I then added some debug code to the reportsview ctor where the crash happens.
We were wondering, because we did not see any debug output. Turns out, that
the missing debug output was caused by a missing configuration in
~/.config/QtProject/qtlogging.ini. Once we turned that on, we saw all the
messages we are used to.

But where's the one I added just infront of the crash location? We saw the
crash happening but no debug output. That is strange. We found out, that
all plugins were build a few moments ago, except the reports plugin which
carried a date of about 4 weeks ago. Strange, but it would explain what is
going on. We manually removed the plugins libraries et voilà: KMyMoney was
running again without crash.

Looking closely at the cmake output, JV spotted that the reports view was
listed among the things that are disabled. Well, that would explain, why it
never replaced the old version. But why did it not get built? Further
investigation showed, that the KChart module (which is a pre-requisite for
the reports plugin) was not found during cmake time. Long story short: the
dev package of it was missing while the library was installed.

How did all this happen: JV build on a prior Fedora version (KChart dev
package was found and the reports plugin was built. Then he upgraded to
Fedora and that apparently removed the KChart dev package. and replaced 
it with KChart6 dev package, but that does not help here and started the
trouble. Then running cmake again, the reports plugin was not built and
installing KMyMoney kept the old version.

Installing the KChart dev package for KF5, rerunning cmake, compiling and
installing brought back the full functionality and JV is a happy camper.
