OK, you will want to add your machine's primary hostname to that. Consider
the case of someone sending to postmaster@???.

Hmm, strange. Have you got the qualify_domain option set to "thaning.se"
by any chance? If so, I'm guessing you then have "root: sten" or similar
in /usr/local/etc/exim/virtual/thaning.se. Not sure why that's not showing
up in exim -bt though.

Although there's nothing wrong with that, it would probably make things
much less confusing if you made the machine "<something>.thaning.se"
rather than "thaning.se". Otherwise, you're pretty much forcing yourself
to mix up what should be local domains and virtual domains. Much better to
have a clear namespace (<something>.thaning.se).
Let me summarise what I would suggest:
primary_hostname = server.example.com
local_domains = server.example.com : localhost
virtual_domains = example.com : other.domains : foo.bar
and then in /path/to/aliases (used just for local_domains):
postmaster: root
abuse: root
root: postmaster@???
... other system aliases
and in /path/to/virtual/example.com:
postmaster: you@???
some.user: user1@localhost
some.other.user: user2@localhost
... other real users
You can see here how the namespaces are all clearly delineated and there
is no confusion. It assumes that user1@localhost and user2@localhost are
"real" Unix users with real mailboxes, and therefore when
some.user@??? gets rewritten to user1@localhost, a real delivery
is made. (This happens by default in Exim thanks to the "localuser"
router, unless you've removed that).
If you were using Courier, or some other mail system with virtual
mailboxes, you might want to invent another private (perhaps unqualified)
domain e.g. "imap", so then you might have:
virtual_mailbox_domains = imap
then in /path/to/virtual/example.com:
...
some.user: user1@imap
...
and then in your routers:
virtual_mailbox_router:
driver = accept
domains = +virtual_mailbox_domains
transport = virtual_mailbox_transport
virtual_mailbox_transport:
<whatever, maybe deliver to a maildir or something>
> I would think that 'primary_hostname = localhost' would take care of

No, don't do that. Leave primary_hostname alone; that should be set to the
true hostname of your machine. It's important for the purposes of
providing meaningful information to others via HELO, SMTP banner, Received
headers etc.
