Was that a security update to a "released" version? Otherwise it's not
so innocent for a production system;)

btw, in future, it is planned to integrate the zope3 tests with
autopkgtest, http://packages.debian.org/unstable/devel/autopkgtest.

Which should mean that this kind of breakage will happen less as
autopkgtest basically is running the tests of installed packages on
installed packages.
