Problems running krb5 telnet

[Jonas Oberg <jonas@coyote.org>]

Hi,

I just compiled heimdal 0.1d so that I'd be able to some krb5 aware
hosts.  kinit and klist works flawlessly, though the telnet client
is giving me trouble.

jonas@poledra:~> telnet -ax host
Encryption is verbose
Trying some.ip...
Connected to host.
Escape character is '^]'.
[ Trying mutual KERBEROS5 ... ]
zsh: abort      telnet -ax host

This is on a Debian GNU machine with a Linux 2.2.3 kernel and glibc 2.1.1.
Any help would be appreciated. A strace of the process doesn't give me much.
It seems to read my ticket file (twice) and then sends a SIBABRT to itself.
