Thanks a lot for your patience with me. I see how I got it wrong now.
However after I've adjusted my configuration to be:

Backup Router
--------------
ServerConnection {
        Host = "dummy";
        Backup = true;
};
RouterConnection {
        Host = "silc.dose.se";
        Port = 706;
        PublicKey = "/opt/etc/silc.dose.se.pub";
        Params = "normal";
        Initiator = true;
};

Primary Router
---------------
ServerConnection {
  Host = "dummy";
};
RouterConnection {
  Host = "silc2.dose.se";
  PublicKey = "/usr/local/etc/silc/silc2.dose.se.pub";
  BackupHost = "silc.dose.se";
  BackupPort = 706;
  BackupLocal = true;
};

I first start up silcd on the primary router like this:

[astan@franz /var/log/silc]$ sudo silcd -D 99
[Logging] [Info] SILC Server started

But then when I start up silcd on the backup router, I get a segfault
on the primary:

[Logging] [Info] Incoming connection h251n2fls33o879.telia.com (213.66.197.251)
Segmentation fault: 11 (core dumped)

It segfaults right at the connection attempt from the backup. Got any
ideas off the top of your head about this, or should I bring out gdb?
:)
