Dear maintainers,

With a recent upload of graphicsmagick the autopkgtest of mpfit fails in
testing when that autopkgtest is run with the binary packages of
graphicsmagick from unstable. It passes when run with only packages from
testing. In tabular form:
                       pass            fail
graphicsmagick         from testing    1.4~hg15968-1
mpfit                  from testing    1.85+2017.01.03-3
all others             from testing    from testing

I copied some of the output to the bottom of this report.

As graphicsmagick isn't automatically triggering autopkgtests for mpfit,
this regression is *not* blocking the migration of graphicsmagick to
testing [1], however not regressing buster is highly appreciated. 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? If needed, please change the bug's severity.
