Test failure in 2.81.4

[ginggs]

I get the following test failures when building the 2.81.4 package for Debian (2.81.3 was fine):

======================================

Preventing the tests from running in parallel allowed them to pass.

i.e. I added the following to debian/rules:

override_dh_auto_test:
    dh_auto_test --no-parallel
