Dear maintainer(s),

With a (not so) recent upload of imagemagick the autopkgtest of 
php-imagick fails in testing when that autopkgtest is run with the 
binary packages of imagemagick from unstable. It passes when run with 
only packages from testing. In tabular form:

                        pass            fail
imagemagick            from testing    8:7.1.2.1+dfsg1-1
php-imagick            from testing    3.8.0-2
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 imagemagick 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?
