Can I suggest that the DNF people ought to be interested in the fact that two
people prepared to say something on this list have a real problem that they
have no idea how to fix without doing a reinstall from scratch.
Sure they are. So far as I'm aware, no-one claimed that the bugs
*aren't* a problem, did they?
It sounds like there is a set up for which there is no problem and
that is
good. It implies there is hope!
If given direction I can create a list of all packages installed, George I
suspect can do likewise. This then might be able to allow people to ascertain
what went wrong, why the tests didn't find it, and (the most important thing)
how to get out of this situation.
It wouldn't hurt (it's easy to do: rpm -qa | sort -u >
packagelist.txt), but it may not necessarily help either. The problem
may not be down to some specific combination of packages, but some
other factor to do with exactly how your repositories are set up or
something like that.
I did an "strace dnf check-update" and got:

Segmentation fault (core dumped)
but that isn't entirely helpful on its own I guess.
No, generally speaking, when you get a core dump, the backtrace of the
core dump (as generated by abrt, if you're lucky) is the most useful
thing you can provide. strace is only helpful in some specific
situations.
