Bug#1121149: pyroute2: autopkgtest regression on s390x

Source: pyroute2
Version: 0.8.1-2
Severity: serious
User: debian-ci@lists.debian.org
Usertags: regression
X-Debbugs-CC: debian-s390@lists.debian.org
User: debian-s390@lists.debian.org
Usertags: s390x
Control: -1 blocks 1119644

Dear maintainer(s),
With a recent upload of pyroute2 the autopkgtest of pyroute2 fails in testing when that autopkgtest is run with the binary packages of pyroute2 from unstable on s390x. It passes when run with only packages from testing. In tabular form: 

                       pass            fail
pyroute2               from testing    0.8.1-2
all others             from testing    from testing

I copied some of the output at the bottom of this report.
Currently this regression is blocking the migration to testing [1]. Can you please investigate the situation and fix it?
