This landed workaround in IPersonSet.ensurePerson needs extension to cover the problem with https://edge.launchpad.net/ubuntu/+source/php-kolab-filter/0.1.5-2/+build/1255703
https://edge.launchpad.net/~math-parent corresponds to an Account associated with a Person and an EmailAddress, but the EA is not linked to the Person. Since ensurePerson() follows EA.person in order to find a suitable Person, it fails.
