octave image test failures with octave 4.0.1

[Orion Poplawski]

I've updated octave to 4.0.1 in Fedora Rawhide.  Now octave-image builds 
are failing running the tests.  See 
https://kojipkgs.fedoraproject.org/work/tasks/2849/13432849/build.log
for full logs.

Is anyone else seeing this?

There were a couple of other updates in addition to octave, so it may be 
something else triggering it.
