  Then the problem isn't the "fix_realm" module.  It's already
returned.

  I think that's the issue.  The "preprocess" module is probably
dying.

  There's no User-Name in the request.  That's wrong, but it shouldn't
cause the server to die.

  When I test it with the above packet, it works for me.  So I'm not
sure what's going wrong.  If you can get a core file, doc/bugs should
help.
