Gmsh 2.11 breaks GmshGrids

[guyer]

With Gmsh 2.11 (and maybe earlier), the GmshGrid tests fail:

It fails for me too. I tried everything: system wide, anaconda virtual environment, from source, pip, different versions of gmsh. The test fails but so does a custom script where I use gmsh commands or when I use a .msh file.
The deb installation of fipy also did not work.
I am using linux mint 17.3 (based on ubuntu 14.04)
