Nothing should have changed to make this necessary.  If you'd like to
help figure out what's going on, comparing the output of
"KRB5_TRACE=/dev/stdout kinit user at IC.AC.UK" on both versions might be
helpful.  Also, finding out the installed krb5 version for each Ubuntu
version ("dpkg -l krb5-user") would be useful.

Also, default_domain is a krb4 relic.  You should never need to set it
any more.
