First, on Nik's advice I ran "/etc/init.d/kdm-trinity restart" which did
nothing.  I then looked at /var/log/Xorg.0.log and found no error messages.

Next, on Dan's advice I ran "apt-get dist-upgrade".  It installed nine
more packages which "apt-get upgrade" for some reason had held back:
iceweasel, kdelibs-trinity, kdelibs4c2a-trinity, kdenetwork-trinity,
kopete-trinity, libgadu3, libmozjs17d, sudo-trinity and xulrunner17.0.

I then ran again "/etc/init.d/kdm-trinity restart".  Lo and behold,
terminal F7 opened with the session manager.  Thanks guys.  Are any of
those packages essential for the desktop environment?

All of the foregoing brought back to memory a thread which I started on
2011-12-16 (KDE-Trinity 3.5.13 hung my machine), where I learned from
several people including Nik that "upgrade" in apt-get is really a
"safe-upgrade".  The latter does not install new versions of currently
installed packages that cannot be upgraded without changing the install
status of another package; it leaves them at their current version.  The
apt-get upgrade seems to be the same as the aptitude safe-upgrade.

The aptitude full-upgrade appears to be similar but not necessarily the
same as the apt-get dist-upgrade. The excerpt from the aptitude manual
for full-upgrade reads as follows:

	Upgrades installed packages to their most recent version, 			removing
or installing packages as necessary. This command is 			less
conservative than safe-upgrade and thus more likely to 			perform
unwanted actions. However, it is capable of upgrading 			packages that
safe-upgrade cannot upgrade.

The excerpt from the apt-get manual for dist-upgrade reads as follows:

	Dist-upgrade in addition to performing the function of upgrade, 		also
intelligently handles changing dependencies with new 			versions of
packages; apt-get has a "smart" conflict resolution 		system, and it
will attempt to upgrade the most important 			packages at the expense of
less important ones if necessary. So, 	dist-upgrade command may remove
some packages.

So I for the foreseeable future I will stick to apt-get but take care to
respect the difference between upgrade and dist-upgrade.
