Hello,
Up to now, I was using FEniCS through the automated build script, and my last build was 1.7.0dev. I just updated to work with FEniCS under docker, so I followed instructions to work with the stable image 2016.2, and everything seemed to work fine (checked some demos and they worked fine). However, I found that in the container, when I try to run one of my old scripts using mshr, I get the following error (minimal code is reproduced at the end). I am stuck cause I am unable to find where this comes from, so I would be grateful if anyone could help me.
Thank you very much for your help.
