The technical 500 debug view and admin email shows the currently logged in
user.
However, if the database is shutting down or is unavailable, anything that
involves the ORM raises `OperationalError`s. Turning `request.user` into a
string in the template rendering will cause and exception which will cause
the rendering to crash. Crashes in the error reporting itself cause hard
to debug problem which can be hard to follow (especially for beginners).
I propose that we should catch exceptions when retrieving the user details
and state that the user could not be shown while still showing everything
else.
