[Pkg-privacy-maintainers] Bug#949252: mat2: autopkgtest needs update for new version of libimage-exiftool-perl

Source: mat2
Version: 0.10.0-1
Severity: serious

Dear maintainers,

With a recent upload of libimage-exiftool-perl the autopkgtest of mat2
fails in testing when that autopkgtest is run with the binary packages
of libimage-exiftool-perl from unstable. It passes when run with only
packages from testing. In tabular form:
                        pass            fail
libimage-exiftool-perl  from testing    11.84-1
mat2                    from testing    0.10.0-1
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
libimage-exiftool-perl to testing [1]. Of course, libimage-exiftool-perl
shouldn't just break your autopkgtest (or even worse, your package), but
it seems to me that the change in libimage-exiftool-perl was intended
(confirmed by gregoa on IRC) and your package needs to update to the new
situation.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from libimage-exiftool-perl
should really add a versioned Breaks on the unfixed version of (one of
your) package(s). Note: the Breaks is nice even if the issue is only in
the autopkgtest as it helps the migration software to figure out the
right versions to combine in the tests.
