Would you mind elaborating, as I'm not able to follow your train
of thought as to why it's clearly my upgrade method.  Even if I
just accept that conclusion, I don't see what to change on my
system to get KDE logouts working.  Do you recommend that I
install some specific packages, remove some specific packages,
change configuration somewhere?

I used the preupgrade method.  I'll spare all of the exact details,
but after upgrading, I ran:
    > yum groupupdate Base "KDE Software Compilation"
to ensure the minimal set of expected packages are installed.

I ran:
    > yum list extras
to make sure there are no lingering packages from Fedora 14.

I used `rpmverify` to verify all packages in the rpm database.
Everything checks out OK, except for some expected configuration
files.

I used `rpm -q -f` on all system files to find and handle any
leftover junk from removed packages.

All of this left me fairly confident that the bits on my HDDs
are correct.  Of course, I may be missing a package or
configuration change that would have happened if I had gone
the route of wiping my HDDs and doing a fresh install.

This was done before my first login to KDE after the upgrade.

I failed to mention in the original post that attempted logouts
leave no traces in system logs or .xsession-errors.
