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?
