Dear maintainer(s),

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

                       pass            fail
breezy                 from testing    3.1~alpha1-1
breezy-loom            from testing    3.0.0-2
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 of breezy 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?
