Bug#1008947: pyresample breaks pytroll-schedule autopkgtest: TestSphericalPolygon.test_bool

Dear maintainer(s),

With a recent upload of pyresample the autopkgtest of pytroll-schedule 
fails in testing when that autopkgtest is run with the binary packages 
of pyresample from unstable. It passes when run with only packages from 
testing. In tabular form:

                        pass            fail
pyresample             from testing    1.23.0-1
pytroll-schedule       from testing    0.6.0-1
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 pyresample 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?
