[R-pkg-team] Bug#952695: r-cran-xml2: autopkgtest failure against libxml2 2.9.10

[Mattia Rizzolo]

Source: r-cran-xml2
Version: 1.2.2-2
Severity: serious
User: debian-ci at lists.debian.org
Usertags: breaks needs-update

Dear maintainer,

With a recent upload of libxml2 the autopkgtest of r-cran-xml2 fails
in testing when that autopkgtest is run with the binary packages of
libxml2 from unstable. It passes when run with only packages from
testing.

I believe this to be a proper behavioural change of libxml2, though I
haven't tracked it down to the changing commit.
