[DRE-maint] Bug#1005032: ruby-hamster: autopkgtest regression: output differ

[Paul Gevers]

Source: ruby-hamster
Version: 3.0.0-4
X-Debbugs-CC: debian-ci at lists.debian.org
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

With a recent upload of ruby-hamster the autopkgtest of ruby-hamster 
fails in testing when that autopkgtest is run with the binary packages 
of ruby-hamster from unstable. It passes when run with only packages 
from testing. In tabular form:

                        pass            fail
ruby-hamster           from testing    3.0.0-4
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?
