[R-pkg-team] Bug#1011412: r-bioc-scater: autopkgtest regression in testing

[Graham Inggs]

Source: r-bioc-scater
Version: 1.18.3+ds-4
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Hi Maintainer

Sometime around 2021-09-23, r-bioc-scater's autopkgtests regressed in
testing [1].
I've copied, from a current log of 1.22.0+ds-2 in unstable, what I
hope is the relevant part below.

Regards
Graham
