How to reproduce:
run-one-until-failure ./bin/test.maas src/maasserver/tests/test_api.py:TestNodeGroupInterfacesAPI.test_new_creates_interface
Analysis of the problem:
In this test, from time to time, 'static_ip_range_high' and 'static_ip_range_low' are 'None' and thus fail the validation (they should be either the empty string or valid IP addresses).
