I don't think this warrants a serious severity, because the samba-libs
package as of oldstable already shipped libndr-krb5pac.so.0.0.1 and if the
only way anyone has filed a bug report about it is after doing a piuparts
test across 4 releases, then the missing Breaks doesn't seem to have had
much practical impact despite the fact that samba4 was entirely obsoleted by
samba version 4.2 (and therefore by samba-libs) in oldstable.
