Description of problem:

A customer experiences DNF command aborting with SIGABRT while libdnf tries to handle the "freeradius" DNF module.
The libdnf code throws a NoModuleException exception which is not caught.

This happens 100% of the time on his system when executing "/usr/bin/dnf update --security".

We hit line 1001. From my understanding, nobody catches the exception so it goes through main, causing the SIGABRT to be raised and a coredump to be created.


Version-Release number of selected component (if applicable):

dnf-4.0.9.2-5.el8
libdnf-0.22.5-5.el8_0


How reproducible:

Always on customer system, never on my test system

Additional info:

The customer doesn't use the standard repos, but his own. It is likely related but I don't have more informations for now.
