Hello,
I haven't programmed in C for a very loooooong time, so my gdb stills are
very rusty (to put it mildly).
After struggling with dnf to get the correct debuginfo for packages (Fedora
seems to be a bit problematic about this), I managed to produce the
following backtrace.
(gdb) bt 20

Does it make any sense? If you give me pointers, I can dig deeper. I
compiled the version from git, but I should be able to repeat the process
with kpa5.3.
Thank you,
