Dear maintainer(s),

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

                       pass            fail
ruby-defaults          from testing    1:2.7+2
rails                  from testing    2:6.0.3.4+dfsg-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. Is this a
(test-)dependency that used to be pulled in?

Currently this regression is blocking the migration of ruby-defaults to
testing [1]. Due to the nature of this issue, I filed this bug report
against both packages. Can you please investigate the situation and
reassign the bug to the right package?
