Thanks for the report.  I can't reproduce this here.

Could you retest with 1:4.2p1-8 in sid?  There were no relevant
changes (noted, anyway) between -7 and -8.

Could you try to get a backtrace?  ulimit -c unlimited should to the
trick, then gdb /usr/sbin/sshd core, then "bt".

Please make sure that you do not have an empty file /etc/krb5.keytab,
as in #349526.
